expand (-3/x)^2

Solution

expand

(- \frac{3}{x})^{2}

Solution

\frac{9}{x ^{2}}

Solution steps

(- \frac{3}{x})^{2}

Apply exponent rule:

(- a)^{n} = a^{n},

if

n

is even

(- \frac{3}{x})^{2} = (\frac{3}{x})^{2}

= (\frac{3}{x})^{2}

Apply exponent rule:

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

= \frac{3 ^{2}}{x ^{2}}

3^{2} = 9

= \frac{9}{x ^{2}}
