How do you know you failed? What's the answer? Maybe your answer can be rewritten to match the correct answer?This is the problem:

This is how I tried to solve it:

I failed badly. How do I do this?

If, in fact, your answer is incorrect, try to

1. Use exponents, not radicals.

2. Don't multiply, keep the original bases and only change exponents (see prev. post re 16).

3. Gradually get rid of the parentheses using the rules of exponents.

4. Change division to multiplication by flipping the sign of the denominator's exponent, e.g.: a/(b^(-2)) = ab^2.

What do you mean by this: 282 ?

Yay! I solved it. It was surprisingly easy with those rules.How do you know you failed? What's the answer? Maybe your answer can be rewritten to match the correct answer?

Honestly I don't know what I meant. I thought I had finished with [imath]16 = 2^4[/imath] !What do you mean by this: 282 ?

\(\displaystyle 16 \ = \ \frac{2^5}{2}\)
