9. (3x2у3)3 =

А. 3x'y"

в. 9x"у"

С. 27xy"

D. 27x"у

Answer 1

`27x^(6) y^(9)`

Explanation:

Given the expression (3x²у³)³, the equivalent expression is simplified using one of the law of indices as shown;

According to the law of indices
`(a^(m))^n = a^(mn)`. Applying this law to the given expression;

`= (3x^(2)y^(3) )^(3) \\\\= (3x^(2) )^(3) * (y^(3))^(3) \\ \\= 3^(3) *(x^(2))^3* (y^(3))^(3)\\\\= 27*x^(6) *y^(9)\\\\= 27x^(6) y^(9)`
