Question

. Find the value of:
(-5)3 × (-1) 7 x 2²​

Answer 1

Answer:

500

Step-by-step explanation:

(-5)³ = -5 * -5 * -5 = -125

(-1)⁷ = -1 * -1 * -1 * -1 * -1 * -1 * -1 = -1

2² = 2 * 2 = 4

∴ (-5)³ * (-1)⁷ * 2² = -125 * -1 * 4 = 125 * 4 = 500

Answer 2

Step-by-step explanation:

(-5)³ × (-1)⁷×2²

= (-5)³ = -5×-5×-5 = -125

= (-1)⁷ =-1×-1×-1×-1×-1×-1×-1 = -1

= 2² = 2×2 = 4

= -125×-1×4

= 125×4

= 500
