simplify (-2)^3*(-2)^4

Solution

simplify

(- 2)^{3} \cdot (- 2)^{4}

Solution

- 128

Solution steps

(- 2)^{3} (- 2)^{4}

Apply exponent rule:

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

(- 2)^{3} (- 2)^{4} = (- 2)^{3 + 4}

= (- 2)^{3 + 4}

Add the numbers:

3 + 4 = 7

= (- 2)^{7}

Apply exponent rule:

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

if

n

is odd

(- 2)^{7} = - 2^{7}

= - 2^{7}

2^{7} = 128

= - 128
