Prime factorization of

90 : 2 \cdot 3^{2} \cdot 5

= 2 2 \cdot 3^{2} \cdot 5

Apply radical rule:

ab = a b, a \geq 0, b \geq 0

2 \cdot 3^{2} \cdot 5 = 3^{2} 2 \cdot 5

= 2 3^{2} 2 \cdot 5

Apply radical rule:

a^{2} = a, a \geq 0

3^{2} = 3

= 2 \cdot 3 2 \cdot 5

Multiply the numbers:

2 \cdot 5 = 10

= 2 \cdot 310

Multiply the numbers:
