If a = -1, b = 2, then find the value of the following: ab × b2

Solution:

Given, a = -1 and b = 2.

Using the law of exponents, we have to find the value of ab × b2

ab × b2 = (-1)2 × (2)2

(-1)2 = -1 × -1 = 1

(2)2 = 4

(-1)2 × (2)2 = 1 × 4

= 4

Therefore, ab × b2 = 4

✦ Try This: If a = 2, b = -2, then find the value of the following: ab × b2
