Bond [772]

Answer: -91

Step-by-step explanation:

(2-5)^2-(4*5^2)

Follow the order of operations.

2-5=-3 Which uses the property of parentheses

(-3)^2-(4*5^2)

(-3)^2=9 which uses the property of exponents

5^2=25 which uses the property of exponents

9-(4*25)

4*25=100 which uses the property of multiplication

=9-100 which uses the property of subtraction
