simplify (-9)^2*(-9)^2

Solution

simplify

(- 9)^{2} \cdot (- 9)^{2}

Solution

6561

Solution steps

(- 9)^{2} (- 9)^{2}

Apply exponent rule:

a^{b} \cdot a^{c} = a^{b + c}

(- 9)^{2} (- 9)^{2} = (- 9)^{2 + 2}

= (- 9)^{2 + 2}

Add the numbers:

2 + 2 = 4

= (- 9)^{4}

Apply exponent rule:

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

if

n

is even

(- 9)^{4} = 9^{4}

= 9^{4}

9^{4} = 6561

= 6561
