High it's me again...

uh how do I write this in SRform?

(7^2^-1+2^2^-1)^2

I tried writing it out in expanded form and
I got
98^2^-1+28^2^-1
which is wrong so how do i do this?

I'm not sure what you mean by "SRform".

I would do the evaluations within the parenthesis before squaring.

(49 - 1 + 4 - 1)^2 = 51^2 = 2601

I hope this helps. If not, repost your question in clearer terms. Thanks for asking.
