Just multiply. \[5*7\sqrt{8*3} \]

what times what gives 24, 6*4 so 35(6)^(1/2)*(4)^(1/2) or \[35\sqrt{4}\sqrt{6}\]

pokemon23Best ResponseYou've already chosen the best response.0
can we simplify it further
 2 years ago

BlingBlongBest ResponseYou've already chosen the best response.2
now you can take the square root of 4 which is 2 therefore you are left with 35(2)(6)^(1/2)

which is just equal to \[70\sqrt{6}\]

if you take the square root of 2 you end up with an irrational number which can only be approximated

Pokemon, you can just use a calculator to check, if you type that in the calculator, it won't equal the same to \[5\sqrt{8}*7\sqrt{3} \]

2*2 is = 4, when you take the square of a number it will tell you what two exact numbers can be multiplied together to give you the original number

Radicals are simply the opposite of exponents. If you had just say 3^(3) = (3)(3)(3) = 27 27^(1/3) =3

BlingBlongBest ResponseYou've already chosen the best response.2
Thus (4)^(1/2) = 2 because 2*2 = 4

You need to memorize the fundamental rule in radicals that (ab)^(1/2) = \[\sqrt{a}\sqrt{b}\]

BlingBlongBest ResponseYou've already chosen the best response.2
if you wish to simplify radicals further, usually I'm to lazy to do this though :d

You can simplify it further but you don't need to, it depends on the question.

In your case 35(24)^(1/2) = \[35\sqrt{6}\sqrt{4}\]
 2 years ago

BlingBlongBest ResponseYou've already chosen the best response.2
since 35 is being multiplied by the radical when (4)^(1/2) is simplified to 2 you are left with 35(2)(6)^(1/2) if you take the square root of 6 you are going to end up with a very ugly number and in mathematics they usually like you to deal with exact numbers

No problem I hope you have gained a better understanding of radicals, I would recommend look up the fundamental rules of radicals
