simplify (r-9)^4(r+9)^4

Solution

simplify

(r - 9)^{4} (r + 9)^{4}

Solution

(r - 9)^{4} (r + 9)^{4}

Solution steps

(r - 9)^{4} (r + 9)^{4}

Apply exponent rule:

a^{m} b^{m} = (ab)^{m},

assuming

a \geq 0, b \geq 0

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

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

Apply exponent rule:

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

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