Question

Which expression is equivalent to 3x^-6y^-3/15x^2y^10

Answer 1

b

Explanation:

Answer 2

The correct option is 2.

Explanation:

The given expression is

`(3x^(-6)y^(-3))/(15x^2y^(10))`

`(x^(-6)y^(-3))/(5x^2y^(10))`

`(x^(-6-2)y^(-3-10))/(5)`
`[\because (x^a)/(x^b)=x^(a-b)]`

`(x^(-8)y^(-13))/(5)`

`(1)/(5x^(8)y^(13))`
`[\because a^(-n)}=(1)/(a^n)]`

Therefore the correct option is 2.
