8(2x-1)^3= 125

i know you could go

(2x-1)^3= 125/8

(2x-1)^3= (5/2)^3

but how can i simplify any further, and yes there is an answer.

**drwls**, Thursday, January 31, 2008 at 8:09pm8 is the cube of 2 and 125 is the cube of 5. Therefore

[2(2x-1)]^3 = 5^3

That means that 2(2x-1) = 5

Take it from there
