Question

Which of the following statements is false?

a. -1-5^2 = -5

b. -(-5) = 5

c. -15^2 = -5

d. (1-5) = -5

Answer 1

Statement c. -15² = -5 is false.

Step-by-step explanation:

Statement c. -15² = -5 is false.

-15² means -1 multiplied by 15 squared.

Squaring a negative number yields a positive result, so -15² is actually equal to -1 * 15 * 15 = -225.

Therefore, the statement -15² = -5 is false.
