Question

What is the solution of log(2x - 3)125 = 3 ?

Answer 1

first change it into exponential form
\[(2x - 3)^3 = 125\]
then get the cube root of both sides
\[\sqrt[3]{(2x-3)^3} = \sqrt[3]{125}\]
\[2x - 3 = 5\]
now it's easy to solve for x

Answer 2

do you get that?

Answer 3

Yeah, is the answer 4?

Answer 4

yup
