simplify (sqrt(7b))^3

Solution

simplify

(7 b)^{3}

Solution

77 b b

Solution steps

(7 b)^{3}

Apply exponent rule:

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

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

= (7 b)^{2} 7 b

Apply exponent rule:

assuming

n i s o dd or a \geq 0

(7 b)^{2} = 7 b

= 7 b 7 b

Apply radical rule:

assuming

a \geq 0, b \geq 0

= 77 b b
