Answer:
Let’s solve the math problem provided in the image:
The expression given is:
42 - (2^2 + 3) + 5 \cdot 3^2
Step-by-step solution:
-
Calculate the exponents:
- (2^2 = 4)
- (3^2 = 9)
-
Substitute back into the expression:
- (42 - (4 + 3) + 5 \cdot 9)
-
Calculate the operations inside the parentheses:
- (4 + 3 = 7)
-
Update the expression:
- (42 - 7 + 5 \cdot 9)
-
Multiply:
- (5 \cdot 9 = 45)
-
Final calculation:
- (42 - 7 + 45)
-
Do the subtraction and addition:
- (35 + 45 = 80)
Therefore, the result of the expression is 80.
