$-\frac{1}{1000}$

okay cool . But how did you get to there?

3. anonymous

Please show the steps :) thank yiou!!!

You can break it into steps with parenthesis: $-(((100^{1/2})^{3})^{-1}$ Evaluate starting at the innermost parenthesis: $-(((10})^{3})^{-1}$ $-(1000}^{-1}$ -(1/1000)

why is it to the exponent 3 and the -1, and not just -3??

6. anonymous

$-100{}^{\wedge}(-3/2)=-\frac{1}{\sqrt[2]{100^3}}=-\frac{1}{\sqrt[2]{1000000}}=-\frac{1}{1000}$

You can do the exponents in any order like (like robtobey).
