Where appropriate, include the approximation to the nearest ten-thousandth.
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.

    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.
