simplify (r+7)(7+r)(r+7)

Solution

simplify

(r + 7) (7 + r) (r + 7)

Solution

(r + 7)^{3}

Solution steps

(r + 7) (7 + r) (r + 7)

Apply exponent rule:

aa = a^{2}

(r + 7) (r + 7) = (r + 7)^{2}

= (r + 7)^{2} (7 + r)

Apply the commutative law:

7 + r = r + 7

= (r + 7)^{2} (r + 7)

Apply exponent rule:

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

(r + 7)^{2} (r + 7) = (r + 7)^{2 + 1}

= (r + 7)^{2 + 1}

Add the numbers:

2 + 1 = 3

= (r + 7)^{3}
