Final answer:
To evaluate -(3⁴²) + 4 x 5, first calculate 3² = 9, then multiply 4 by 5 to get 20, and ultimately add -9 to 20 to find the answer of 11.
Step-by-step explanation:
The student is asking to solve the following expression: -(3⁴²) + 4 x 5. First, apply exponentiation: 3⁴² means 3 raised to the power of 2, which is 3 x 3 = 9. Thus, the expression becomes -9 + 4 x 5. Then apply the order of operations (PEMDAS/BODMAS), which requires solving multiplication before addition and subtraction. Therefore, multiply 4 by 5 to get 20. The expression now simplifies to -9 + 20. Finally, add -9 to 20, which results in 11.
