(-7)⁵ × (-7)³ is equal to
a. (-7)⁸
b. -(7)⁸
c. (-7)¹⁵
d. (-7)²

Solution:

Given, the expression is (-7)⁵ × (-7)³

We have to find the value of the expression

For any non-zero integers ‘a’ and ‘b’, and whole numbers m and n,

a^m × aⁿ = a^m+n

Here, a = -7, m = 5 and n = 3

So, m + n = 5 + 3 = 8

Therefore, (-7)⁵ × (-7)³ = (-7)⁸
