Question

Consider the following equation. 1000=5(10^2t) which of the following equations can be used to find true value of t. A.log2(1000) B.log2(200)=10t C.log10(1000)=5(2t) D.log10(200)=2t

Answer 1

D. log₁₀(200) = 2t

Explanation:

Dividing by 5 gives you ...

... 200 = 10^(2t)

Taking the log to the base 10 gives you ...

... log₁₀(200) = 2t . . . . . . matches selection D
