expand p^{1/4}(p^{3/4}+3p^{7/4})

expand

p^{\frac{1}{4}} (p^{\frac{3}{4}} + 3 p^{\frac{7}{4}})

p + 3 p^{2}

Solution steps

p^{\frac{1}{4}} (p^{\frac{3}{4}} + 3 p^{\frac{7}{4}})

Apply the distributive law:

a (b + c) = ab + a c

p^{\frac{1}{4}} (p^{\frac{3}{4}} + 3 p^{\frac{7}{4}}) = p^{\frac{1}{4}} p^{\frac{3}{4}} + p^{\frac{1}{4}} \cdot 3 p^{\frac{7}{4}}

= p^{\frac{1}{4}} p^{\frac{3}{4}} + p^{\frac{1}{4}} \cdot 3 p^{\frac{7}{4}}

p^{\frac{1}{4}} p^{\frac{3}{4}} = p

p^{\frac{1}{4}} \cdot 3 p^{\frac{7}{4}} = 3 p^{2}

= p + 3 p^{2}

A (- 2, 22) B (13, - 19)

x (x + 1) (x + 2) (x + 3) + 1

\frac{π t ( 3 + 2 n )}{6}

(x sin (θ) - y sin (θ))^{2}

(6 t^{2} - 2 t + 13 - 3 t) \cdot (- 3, - 1)
