Exponents

[smileypup21]

Hi, i am new here and i am stuck with this question. It is " Use your knowledge of exponent laws to determine the value of A in the following problem. Prove that your answerrs work by subbing them into the question and simplifying."

(125)-4 = 6561
A 3 625

That's a bit hard to read.

Did you mean $\displaystyle \left(\frac{125}{A}\right)^{-\frac{4}{3}}=\frac{6561}{625}$?

And why is it you are stuck? Where, specifically are you having a problem?
