Question

Use laws of exponents to simplify inside the parentheses of the given expression ((a ^ - 2 * b ^ 2)/(a ^ 2 * b ^ - 1)) ^ - 3

Answer 1

its d

Explanation:

ur welcome

Answer 2

Explanation:

`[((a^(-2)*b^(2)))/((a^(2)*b^(-1)))]^(-3)=(a^(-2-2)*b^(2+1))^(-3)\\\\\\=(a^(-4)*b^(3))^(-3)=(a^(-4))^(-3)*(b^(3))^(-3)\\\\=a^(-4*-3)*b^(3*-3)=a^(12)*b^(-9)\\\\=(a^(12))/(b^(9))`

Hint:
`a^(-m)=(1)/(a^(m))\\\\a^(m)*a^(n)=a^(m+n)\\\\(a^(m))^(n)=a^(mn)\\`
