expand (1/(3-y))^3

Solution

expand

(\frac{1}{3 - y})^{3}

Solution

\frac{1}{27 - 27 y + 9 y ^{2} - y ^{3}}

Solution steps

(\frac{1}{3 - y})^{3}

Apply exponent rule:

(\frac{a}{b})^{c} = \frac{a ^{c}}{b ^{c}}

= \frac{1 ^{3}}{( 3 - y ) ^{3}}

Apply rule

1^{a} = 1

1^{3} = 1

= \frac{1}{( 3 - y ) ^{3}}

(3 - y)^{3} = 27 - 27 y + 9 y^{2} - y^{3}

= \frac{1}{27 - 27 y + 9 y ^{2} - y ^{3}}
