simplify (8d^4)(-8d^4)

Solution

simplify

(8 d^{4}) (- 8 d^{4})

Solution

- 64 d^{8}

Solution steps

(8 d^{4}) (- 8 d^{4})

Apply rule:

a (- b) = - ab

(8 d^{4}) (- 8 d^{4}) = - 8 d^{4} \cdot 8 d^{4}

= - 8 d^{4} \cdot 8 d^{4}

Multiply the numbers:

- 8 \cdot 8 = - 64

= - 64 d^{4} d^{4}

Apply exponent rule:

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

d^{4} d^{4} = d^{4 + 4}

= - 64 d^{4 + 4}

Add the numbers:

4 + 4 = 8

= - 64 d^{8}
