Where appropriate, include the approximation to the nearest tenthousandth.
24.) 3^x= 1/81
25.) logx 125 =3
26.) log64 x = 1/2

These are extraordinarily easy. For instance, what is 5 cubed?
I will be happy to critique your thinking.

Where appropriate, include the approximation to the nearest tenthousandth.
24.) 3^x= 1/81 I have x = 1/5
25.) logx 125 =3 I have x = 5
26.) log64 x = 1/2 I have x = 8
Are these answers right?

on the first, log3 of each side
x= log3 81=4
others are right.
