simplify 4sqrt(5a)*2sqrt(40ab)

simplify

4 5 a \cdot 2 40 ab

802 a b

Solution steps

4 5 a \cdot 2 40 ab

Simplify

5 a : 5 a

= 45 a \cdot 2 40 ab

Simplify

40 ab : 210 a b

= 45 a \cdot 2 \cdot 210 a b

Apply radical rule:

a a = a,

assuming

a \geq 0

a a = a

= 45 a \cdot 2 \cdot 210 b

10 = 52

= 45 a \cdot 2 \cdot 252 b

Apply radical rule:

a a = a, a \geq 0

55 = 5

= 4 \cdot 5 a \cdot 2 \cdot 22 b

Multiply the numbers:

4 \cdot 5 \cdot 2 \cdot 2 = 80

= 80 a 2 b

= 802 a b

- 16 x^{2} + 36

x + \frac{x}{2 x}

\frac{- 8 x + 3}{2 x + 7} - \frac{- 3 x + 6}{2 x + 7}

\frac{8 x ^{2} y ^{2}}{4 x ^{2} y ^{6}}
