simplify 5sqrt(80a^2)

Solution

simplify

5 80 a^{2}

Solution

205 a

Solution steps

5 80 a^{2}

Apply radical rule:

ab = a b,

assuming

a \geq 0, b \geq 0

80 a^{2} = 80 a^{2}

= 580 a^{2}

80 = 45

= 5 \cdot 45 a^{2}

Apply radical rule:

a^{2} = a,

assuming

a \geq 0

a^{2} = a

= 5 \cdot 45 a

Multiply the numbers:

5 \cdot 4 = 20

= 205 a
