Question 27 Exponents and Powers - Exercise

(-1/4)3 × (-1/4) = (-1/4)11

Answer:

-1/4)3 × (-1/4)8 = (-1/4)11

We know that,

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

a m × an = am+n

Let us assume missing power be y,

Then, (-1/4)3 × (-1/4)y = (-1/4)11

(-1/4)y = (-1/4)11/(-1/4)3

(-1/4)y = (-1/4)11 - 3

(-1/4)y = (-1/4)8
