simplify (4t^3-5)2

Solution

simplify

(4 t^{3} - 5) 2

8 t^{3} - 10

Solution steps

(4 t^{3} - 5) \cdot 2

= 2 (4 t^{3} - 5)

Apply the distributive law:

a (b - c) = ab - a c

2 (4 t^{3} - 5) = 2 \cdot 4 t^{3} - 2 \cdot 5

= 2 \cdot 4 t^{3} - 2 \cdot 5

Simplify

2 \cdot 4 t^{3} - 2 \cdot 5 : 8 t^{3} - 10

= 8 t^{3} - 10

(81 m^{4} + \frac{1}{3 m})^{25}

\frac{x - 20}{x ^{2} - 4 x} + \frac{x}{x - 4}

(- 3 m^{3} n^{4})^{4}

\frac{4 x ^{2} - 1}{2 x ^{2} - x - 1}

\frac{3}{2} \cdot 0
