Question

2. Express each of the following as a rational number in the form of p/q
Where q≠0

Answer 1

Explanation:

We need to find each of the following as a rational number in the form of p/q

(a) (3/7)² (b) (7/9)³ (c) (-2/3)⁴

Solution,

(a) (3/7)²

`((3)/(7))^2=(9)/(49)`

(b) (7/9)³

`((7)/(9))^3=(7* 7* 7)/(9* 9* 9)\\\\=(343)/(729)`

(c) (-2/3)⁴

`((-2)/(3))^4=(-2* -2* -2* -2)/(3* 3* 3* 3)\\\\=(16)/(81)`

Hence, this is the required solution.
