simplify (-9a^3b)^2

Solution

simplify

(- 9 a^{3} b)^{2}

Solution

81 a^{6} b^{2}

Solution steps

(- 9 a^{3} b)^{2}

Apply exponent rule:

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

if

n

is even

(- 9 a^{3} b)^{2} = (9 a^{3} b)^{2}

= (9 a^{3} b)^{2}

Apply exponent rule:

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

(9 a^{3} b)^{2} = 9^{2} (a^{3})^{2} b^{2}

= 9^{2} (a^{3})^{2} b^{2}

9^{2} = 81

= 81 (a^{3})^{2} b^{2}

Simplify

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

= 81 a^{6} b^{2}
