# Out of the four options, only one is correct. Write the correct answer.For a non-zero integer x, x7 ÷ x12 is equal toA. x5B. x19C. x–5D. x–19

By laws of exponent,

xm ÷ xn = xm-n

In this question,

m = 7

n = 12

xm ÷ xn = xm-n

x7 ÷ x12 = x7-12

x7 ÷ x12 = x-5

Hence, for a non-zero integer x, x7 ÷ x12 is equal to x-5.
