Answer

Error: Does not compute inside parenthesis first Answer: 103

Work Step by Step

For solving every problem, we have to use order of operations (PEMDAS). First, is parenthesis, which means we have to solve whatever is inside the parenthesis first. The problem however does the exponent first, which is wrong. Fixing the error: $3 + (2*5)^2$ By PEMDAS, parenthesis goes first: $3 + (10)^2$ Then, the E in PEMDAS stands for exponents, so we calculate the exponent. $3 + (10*10) = 3 + 100$ Because we do not have any multiplication or division, we go to A, which is addition: $ 3 + 100 = 103$
