simplify (r^4)(-3r^4)

Solution

simplify

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

Solution

- 3 r^{8}

Solution steps

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

Simplify

(r^{4}) (- 3 r^{4}) : - r^{4} (3 r^{4})

= - r^{4} \cdot 3 r^{4}

Apply exponent rule:

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

r^{4} r^{4} = r^{4 + 4}

= - r^{4 + 4} \cdot 3

Add the numbers:

4 + 4 = 8

= - r^{8} \cdot 3

= - 3 r^{8}
