Question

Don't know this one, please help

Answer 1

D. 54/n¹¹

Explanation:

(6n⁻⁵)(3n⁻³)²

Note that (ax)ᵇ=aᵇxᵇ

(6n⁻⁵)(3²)(n⁻³)²

(6)(n⁻⁵)(9)(n⁻³)²

54(n⁻⁵)(n⁻³)²

Note that (xᵃ)ᵇ=xᵃᵇ

54(n⁻⁵)(n⁻³⁽²⁾)

54(n⁻⁵)(n⁻⁶)

54(n⁻⁵)(n⁻⁶)

54(n⁻⁵)(n⁻⁶)

Note that (xᵃ)(xᵇ)=xᵃ⁺ᵇ

54(n⁻⁵⁻⁶)

54n⁻¹¹

Note that x⁻ᵃ=1/xᵃ

54/n¹¹

Answer 2

D) 45/n 11

Explanation:

(6n^-5(3n^-3)

= 6n^-5×9n^-6

= 54n ^-11

= 54/n 11

hope it helps..
