Answer:
According to the order of operations, we first evaluate the exponent, then multiply and divide from left to right, and then add and subtract from left to right.
Therefore, the expression is evaluated as follows:
7 • 5 + 4 power 2 - 2 power 3 ÷ 4
= 7 • 5 + 4 * 4 - 2 * 2 * 2 / 4
= 35 + 16 - 4
= 47
Therefore, the answer is 47.
