I failed badly. How do I do this?
What do you mean by this: 282 ?Okay, I don't know about you but the whole ratio symbol thing mixes me up. Anyway, the first thing I'd do would be to change [imath]16 = 2^4 = 2^{8}{2}[/imath]. Leave everything in terms of powers... don't multiply anything out. See if that helps.

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?
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.
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 ?
I think you tried to write:Honestly I don't know what I meant. I thought I had finished with [imath]16 = 2^4[/imath] !
