Prime factorization of

8 : 2^{3}

= 7 2^{3}

Apply exponent rule:

a^{b + c} = a^{b} \cdot a^{c}

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

= 7 2^{2} \cdot 2

Apply radical rule:

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

2^{2} \cdot 2 = 2^{2} 2

= 7 2^{2} 2

Apply radical rule:

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

2^{2} = 2

= 7 \cdot 22

Multiply the numbers:

7 \cdot 2 = 14

= 142
