Evaluate.
128 ÷(5^2 + 7)
128÷ (25 + 7) = 128 ÷32 = 4 correct?
excellent.
Yes, that is correct. To evaluate the expression 128 ÷ (5^2 + 7), we need to follow the order of operations, also known as PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction):
1. Evaluate the exponent: 5^2 = 5 × 5 = 25.
2. Add the result of the exponent to 7: 25 + 7 = 32.
3. Divide 128 by the sum of 32: 128 ÷ 32 = 4.
So, the value of the expression is indeed 4.
