Prime factorization of

84 : 2^{2} \cdot 3 \cdot 7

= 2^{2} \cdot 3 \cdot 7

Apply radical rule:

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

2^{2} \cdot 3 \cdot 7 = 2^{2} 3 \cdot 7

= 2^{2} 3 \cdot 7

Apply radical rule:

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

2^{2} = 2

= 2 3 \cdot 7

Multiply the numbers:

3 \cdot 7 = 21

= 221
