Question

Is anyone really good at log???? Please let me know now!!:)

Answer 1

you really should post an actual problem that you might need help on ....

Answer 2

hmmm, thats saying that 4^x = 32

Answer 3

8?

Answer 4

nevermind

Answer 5

4 = 2^2; 32 = 2^5

\[2^{2x}=2^{5}~;~ 2x=5\]is what my first idea is

Answer 6

\[log_4(32)\]
\[\frac{log_2(32)}{log_2(4)}\]
\[\frac{5}{2}\]
same same

Answer 7

\[log_4(32)\]
\[log_4(4*4*2)\]
\[log_4(4)+log_4(4)+log_4(2)\]
\[1+1+\frac12=\frac52\]

Answer 8

i would log 25 each side

Answer 9

25^x-2=125

log_25(25^x-2)=log_25(125)

(x-2) log_25(25)=log_25(125)

x-2 =log_25(25*5)

x-2 =log_25(25) + log_25(5)

x-2 = 1 + 1/2

x = 2 + 1 + 1/2
