expand 7a^3((a^2+b)(7ab-4ab^4))

expand

7 a^{3} ((a^{2} + b) (7 ab - 4 a b^{4}))

49 a^{6} b - 28 a^{6} b^{4} + 49 a^{4} b^{2} - 28 a^{4} b^{5}

Solution steps

7 a^{3} ((a^{2} + b) (7 ab - 4 a b^{4}))

Remove parentheses:

(a) = a

= 7 a^{3} (a^{2} + b) (7 ab - 4 a b^{4})

Expand

(a^{2} + b) (7 ab - 4 a b^{4}) : 7 a^{3} b - 4 a^{3} b^{4} + 7 a b^{2} - 4 a b^{5}

= 7 a^{3} (7 a^{3} b - 4 a^{3} b^{4} + 7 a b^{2} - 4 a b^{5})

Expand

7 a^{3} (7 a^{3} b - 4 a^{3} b^{4} + 7 a b^{2} - 4 a b^{5}) : 49 a^{6} b - 28 a^{6} b^{4} + 49 a^{4} b^{2} - 28 a^{4} b^{5}

= 49 a^{6} b - 28 a^{6} b^{4} + 49 a^{4} b^{2} - 28 a^{4} b^{5}
