Best ResponseYou've already chosen the best response.1don't use calculator forsqrt{700} there is a negative sign so you should get imaginary solution so factor out the 700 what is the largest factor of 700 that should be the perfect square root

Best ResponseYou've already chosen the best response.0idk a perfect sqrt for 700 close ive got is 26.4 and thats a decimal

Best ResponseYou've already chosen the best response.1hmm 350 isn't a perfect square root what two numbers would you multiply to get 700 ??

Best ResponseYou've already chosen the best response.1like i said \[\sqrt{350} = 18.7\] you will get decimal answer so 350 isn't a perfect square what are the factors of 700 ?

Best ResponseYou've already chosen the best response.0what factors do you mean? like single digit numbers?

Nnesha

Best ResponseYou've already chosen the best response.1yes like factors of 9 are 1 and 3 ,9 in other words 9 is divisible by 1 and 3 and 9

Best ResponseYou've already chosen the best response.01, 2, 4, 5, 7, 10, 14, 20, 25, 28, 35, 50, 70? do any those work?

Best ResponseYou've already chosen the best response.0if not im not sure what other factors their are for 700

Best ResponseYou've already chosen the best response.1what about 100 ? we need GREATEST factor

Nnesha

Best ResponseYou've already chosen the best response.17 times 100 = 700 and 100 is perfect square root ?

Best ResponseYou've already chosen the best response.0so what do I do with this 700 then now that we figured out the two multiples?

Nnesha

Best ResponseYou've already chosen the best response.1yes right so we can writeh 700 as 1*7*100 100 bec we need greatest factor and sqrt{1} bec we can change that to i \[\huge\rm \sqrt{1} =i\]

Nnesha

Best ResponseYou've already chosen the best response.1\[\huge\rm \frac{ 10 \pm \sqrt{1 \times 100 \times 7} }{ 2 }\] sqrt{100} = 10 and replace sqrt{1} with i

Best ResponseYou've already chosen the best response.0ah ha ok ok quick questions Im not sure if what I learned is the best method for a short cut but can I divide both the 10 and that sqrt by 2? and then I believe there is some final step afterwards.

Nnesha

Best ResponseYou've already chosen the best response.1first deal with the square root part then you can take out the common factor at the numerator after that you will be able to divide by 2

Best ResponseYou've already chosen the best response.0alright so whats next then?

Nnesha

Best ResponseYou've already chosen the best response.1alright so sqrt{700}= what ??(not the decimal answer)

some.random.cool.kid

Best ResponseYou've already chosen the best response.0xD thats funny because I was about to put the decimal again thanks for clarifying lol. So based off of what I see you've got the 7 and 100 as your two multiples correct?

Best ResponseYou've already chosen the best response.1\[\huge\rm \frac{ 10 \pm \sqrt{\color{Red}{1 \times 100 \times 7}} }{ 2 }\] that's what we got whenever you see negative sign under the square root you should know that u have to take out the negative 1 so we can convert it to i

Nnesha

Best ResponseYou've already chosen the best response.1\[\huge\rm \frac{ 10 \pm \sqrt{\color{Red}{1 \times 100 \times 7}} }{ 2 }\] can be written as \[\frac{ 10 \pm \sqrt{1}\sqrt{100}\sqrt{7} }{ 2}\]

Best ResponseYou've already chosen the best response.0sqrt of 100 10x10?

Nnesha

Best ResponseYou've already chosen the best response.1you can write 100 as 10 times 10 (and when we multiply same bases we should `ADD` their exponents ) so 10 times 10 = 10^2 sqrt{10^2} =?

some.random.cool.kid
 one year ago
Best ResponseYou've already chosen the best response.0wait isn't the sqrt of 10^2 the same as saying just 10?

Best ResponseYou've already chosen the best response.1dw:1442804384787:dw there is no `eye`(i) in first term

some.random.cool.kid

Best ResponseYou've already chosen the best response.0the only common I see is the 7 and 10 because they are like terms where as the 10i is not same

some.random.cool.kid

Best ResponseYou've already chosen the best response.0no in second term you drew in extra line so I couldnt tell I was asking if that was an i

Nnesha

Best ResponseYou've already chosen the best response.1let me explain dw:1442804430474:dw there are two box red and blue what is the common number in both terms ?

some.random.cool.kid

Best ResponseYou've already chosen the best response.0well there is two 10's?

some.random.cool.kid

Best ResponseYou've already chosen the best response.0ok so ow your left with i x sqrt of 7?

Nnesha

Best ResponseYou've already chosen the best response.1what will you get when you take out 10 from 10?

Nnesha
 one year ago
Best ResponseYou've already chosen the best response.1or in other words divide 10 by common factor so 10/10 = ?

some.random.cool.kid
 one year ago
Best ResponseYou've already chosen the best response.0or is it i = sqrt of 7 and doesn't that cancel out?

some.random.cool.kid
 one year ago
Best ResponseYou've already chosen the best response.0that should cancel out because one is negative and both same numbers

Nnesha

Best ResponseYou've already chosen the best response.1no 2/2 would be 1 so 10/10 ?

Nnesha
 one year ago
Best ResponseYou've already chosen the best response.1yes right \[\frac{ 10(1 \pm i \sqrt{7} )}{ 2 }\]

Nnesha
 one year ago
Best ResponseYou've already chosen the best response.1NOW you can divide 10 by 2

some.random.cool.kid

Best ResponseYou've already chosen the best response.0so thats 5 uh one minute? you mean or like candy mint

Nnesha

Best ResponseYou've already chosen the best response.1\[ 5(1 \pm i \sqrt{7})\] now you can distribute by 5

some.random.cool.kid

Best ResponseYou've already chosen the best response.0because i needed help with one more but if you have to go i can respect that

Nnesha
