Hello from MrBillDoesMath!


Answer:  4a^2 + 25b^2


Discussion.  First, I write the square of a number using the notation "^" which appear on the 6 key of the keyboard. As 3 times 3, or 3 squared, is 9, this becomes 3^2 = 9.

I interpreted you question as asking for the value of

(2a)^2 + (5b) ^ 2 =  (2a)(2a) + (5b)(5b) = 4a^2 + 25b^2.


Regards, MrB.
