logarithm problem

**maths_cat** · February 26th 2009, 11:23 AM

I can't figure out how to solve this for x

13 + log2 x^(-3) = -22

this apparently simplifies to x = 2^(35/3)

could somebody please tell me how to solve this one?

thankyou

Is the equation $13 + log(2) x^{-3}=-22$ or $13 + log(2x^{-3})=-22$ ?
