Does someone mind helping me with this problem? Thank you!
faltersainse [42]

\frac{10-(3 \cdot 2^2 - 23)}{(1 + 10^2)-2^2 \cdot 5^2} =

10-\left(3\cdot \:2^2-23\right) =10-\left(-11\right) =21

\left(1+10^2\right)-2^2\cdot \:5^2 =  101-2^2\cdot \:5^2 = 101-4\cdot \:5^2 =101-4\cdot \:25 =101-100 = 1

=\frac{21}{1}

\frac{a}{1}= a

=21

I hope I helped you!
