simplify (-9w^3u)^2

Solution

simplify

(- 9 w^{3} u)^{2}

Solution

81 w^{6} u^{2}

Solution steps

(- 9 w^{3} u)^{2}

Apply exponent rule:

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

if

n

is even

(- 9 w^{3} u)^{2} = (9 w^{3} u)^{2}

= (9 w^{3} u)^{2}

Apply exponent rule:

(a \cdot b)^{n} = a^{n} b^{n}

(9 w^{3} u)^{2} = 9^{2} (w^{3})^{2} u^{2}

= 9^{2} (w^{3})^{2} u^{2}

9^{2} = 81

= 81 (w^{3})^{2} u^{2}

Simplify

(w^{3})^{2} : w^{6}

= 81 w^{6} u^{2}
