Given that the expression you're trying to simplify looks like this --- (u^{-6})^{2} --- here's how I would start to tackle it.

**Expression: (u ^{-6})^{2
}Multiply the exponents: u**

Then, it's important to know that

Hi Angela!

You could simply but surely "type out" the expression:

u^-1= 1/u ==> u^-6= 1/(u*u*u*u*u*u), now squaring this thing means you'll have twice as many u's ...

Since (1/u)^2= (1/u)(1/u) ==> (1/u^6)(1/u^6)= 1/(u^12) Best wishes, ma'am :)
