Answer 1

\[4^{x}=8\]

Answer 2

i thought the answer was \[\frac{ \log8 }{ \log4 }\] but apparently it's 3/2 and i wanna know what i got wrong.

Answer 3

or how you get 3/2

Answer 4

4 = 2^2

8 = 2^3

Answer 5

4^x = 8

(2^2)^x = 2^3

2^(2x) = 3

The bases are equal, so the exponents must be equal as well meaning that

2x = 3

x = 3/2

Answer 6

ahh, i see

Answer 7

btw you would get the same answer if you typed in log(8)/log(4) since that does simplify to 3/2

Answer 8

your calculator will spit out 1.5, but that's the same thing as 3/2
