Evening, Question: (10^1 + 10^2)^1 I've tried this a couple different ways, I'm sure I'm missing something simple. I know the answer is 100/11. If somebody could explain/show me the process to get to the correct answer it would be greatly appreciated Thanks, ~Lena

Pretty sure I figured it out. If this isn't correct, please correct me Just in case others weren't sure: = 1 / (10^1 + 10^2)^1 = 1/1 ÷ (1/10^1 + 1/10^2) = 1/1 ÷ (1/10 + 1/100) = 1/1 ÷ (11/100 + 1/100) = 1/1 ÷ 11/100 = 1/1 X 100/11 = 100/11 Thanks.

(10^1 + 10^2)^1 = (.1 + .01)^1 = .11^1 = 100/11.
