Question

Solve 4^x = 12

Answer 1

4^x = 12

ln(4^x) = ln(12)

x *ln(4) = ln(12)

x = ln(12)/ln(4)

ln is the natural logarithm

Answer 2

we can use logs here.....when you have something like
4^x = 12
taking the log of 4^x turns it into xlog4

it brings the exponent in front of log4

so we have

xlog4 = log12 (must do it to the other side to remain equal)
so

x = log12/log4

Answer 3

these are the answer choices... x ≈ 0.27

x ≈ 0.56

x ≈ 1.79

x ≈ 19.93

Answer 4

and no...it doesnt matter if you use ln or log...same answer

Answer 5

well evaluate it...what is log12....divided by log4?

Answer 6

3..?

Answer 7

do you have a calculator with you? just type in log12..close the parenthsis...then divide it by log4

Answer 8

only have a basic calculator

Answer 9

oh...okay well i'll do this for you then

log12/log4 = 1.79

Answer 10

thank you

Answer 11

anytime :)
