Question

13. (4r⁰)⁴
14. (4a³)²
15. (3k⁴)⁴
16. (4xy)⁻¹
17. (2b⁴)⁻¹
18. (x²y⁻¹)₂

Answer 1

Explanation:

13.

(4r⁰)⁴

= (4×1)⁴

= (4)⁴

= 256

14.

(4a³)²

`= 4^2a^((3* 2))`

= 16 a⁶

15.

(3k⁴)⁴

`= 3^4 k^(4*4)`

`= 81 \ k^(16)`

16.

(4xy)⁻¹

`= (1)/(4 xy)`

17.

(2b⁴)⁻¹

`= (1)/(2 \ b^4)`

18.

(x²y⁻¹)²

`=\Big ( (x^2)/(y) \Big) ^ 2`

`=\Big ( (x^4)/(y^2) \Big)`
