Answer:
49
Step-by-step explanation:
Follow the PEMDAS rule.
P- Parenthesis
E- Exponents
M- Multiplication
D- Division
A-Addition
S-Subtraction
Following this rule, you would add 3+4, which gets you 7.
Then, you would multiply 7 by 7, as that is what the exponent, two suggests
7x7 = 49.
thus,
(3 + 4)² = 49
