Best ResponseYou've already chosen the best response.0Typo on last post it should be: 3^(3x1)=9^(x3)

Best ResponseYou've already chosen the best response.0first u note that 9^(x3) = 3^[2(x3)] therefore; 3x1=2(x3). solve this to get x.

Best ResponseYou've already chosen the best response.0where did the two come from?

Best ResponseYou've already chosen the best response.0as example, 9^2=3^(2*2)=81. thats the same i done above. but instead of integer, the power in the question is an equation.

Best ResponseYou've already chosen the best response.0ok so if i have a problem like 3^(4x2)=27^(x) then it would be 4x2=3(x)??

Best ResponseYou've already chosen the best response.0now what if i got a^(x4)=[a^6][a^(3x6)]

Best ResponseYou've already chosen the best response.0let say u hav (2^3)*(2^5), this wil be equal to 2^(3+5) so in ur case, [a^6][a^(3x6)]=a^[6+(3x6)]

smurfy14

Best ResponseYou've already chosen the best response.0so then you would do a^x4=a^[6+(3x6)] and then what do you do next?

anonymous

Best ResponseYou've already chosen the best response.0yup.then do same as before, equate the power to get the x. x4=6+(3x6)

Best ResponseYou've already chosen the best response.0alright now if you have a problem 9^(2x+1)=27^(x+2) then you have 2x+1=???

Best ResponseYou've already chosen the best response.0in this case, first u need to make the "base" equal. note that 9=3^2 and 27=3^3. therefore,the eqn become: 3^[2(2x+1)]=3^[3(x+2)] then equate the power as usual: 2(2x+1)=3(x+2)

Best ResponseYou've already chosen the best response.0ok so now i have 5^(2x+3)=(square root of 5)^(x+4)

anonymous

Best ResponseYou've already chosen the best response.0u can write square root of 5 as 5^(1/2) then u can proceed with 2x+3= (1/2)*(x+4)

Best ResponseYou've already chosen the best response.0why do you write it as 1/2? how did you get that

anonymous

Best ResponseYou've already chosen the best response.0dont have to calculate anything for that. its basic rule how to write it a square root. \[\sqrt[m]{A} = A ^{1/m}\]

Best ResponseYou've already chosen the best response.0ohh ok haha also, i have (2a)^x=(4a^2)^x+2 and so would it be x=2(x+2)?

Best ResponseYou've already chosen the best response.0if the ratio of snicker to m&m's is 5 to 6 then the store could have

Best ResponseYou've already chosen the best response.0and on the last problem with the 1/2... what would the answer be?

anonymous

Best ResponseYou've already chosen the best response.0i think it is x=2/3. u got the same?

Best ResponseYou've already chosen the best response.0no i got something different :/ umm i guess i did it wrong because i think you are right

Best ResponseYou've already chosen the best response.0try check it again. maybe a careless mistake.

Best ResponseYou've already chosen the best response.0ok now i got it :) okay well to switch gears a bit.. now i have to do log(3/5)(25/9)=x+4 **3/5 is the little bottom number**

anonymous

Best ResponseYou've already chosen the best response.0remember that if \[\log_{a} b = c \] this implies\[a ^{c}=b\] so, u hav to change the initial problem into the 2nd form. and u also hav to note that 25/9= (3/5)^2

anonymous

Best ResponseYou've already chosen the best response.0no. 25/9= (5/3)^2 = (3/5)^2

Best ResponseYou've already chosen the best response.0ohh ok! im sorry to be asking so many questions its just that im so confused! ok on 2^x * 4^(x+5)=4^(2x1) what do you do next?

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0since 4=2^2, then the eqn becomes; 2^x * 2^[2(x+5)]=2^[2(2x1)] this implies; 2^[x+2(x+5)]=2^[2(2x1)] therefore, x+2(x+5)=2(2x1)

Best ResponseYou've already chosen the best response.0ohh ok umm what did you get on the previous problem? i dont know where x is supposed to go when you solve. i got this: (3/5)^4=(3/5)^2

anonymous

Best ResponseYou've already chosen the best response.0it should be (3/5)^(x+4)=(3/5)^2 x included in "c" based on the general form i gave u before.
