expand (x+y)a^3+(x+y)b^2

expand

(x + y) \cdot a^{3} + (x + y) \cdot b^{2}

x a^{3} + a^{3} y + x b^{2} + y b^{2}

Solution steps

(x + y) a^{3} + (x + y) b^{2}

= a^{3} (x + y) + b^{2} (x + y)

Expand

a^{3} (x + y) : x a^{3} + a^{3} y

= x a^{3} + a^{3} y + b^{2} (x + y)

Expand

b^{2} (x + y) : x b^{2} + y b^{2}

= x a^{3} + a^{3} y + x b^{2} + y b^{2}

(a - 4) (a - 2)^{2} (a - 1)^{7}

\frac{( - 5 x ^{- 2} y ^{- 2} z ) ^{2}}{( 1 0 ^{- \frac{1}{3}} x ^{\frac{2}{3}} y z ^{- \frac{2}{3}} ) ^{- 3}}

\frac{5 a ^{m} ( 5 b ^{m} ) ^{2}}{( ( a ^{2} ) ^{m} ) ^{2}}

(- 2 x^{a - 2}) (7 x^{5} - 8 x^{2} + 6 x^{3} - 9 x + 2)
