Prime factorization of

640 : 2^{7} \cdot 5

= 2^{7} \cdot 5

Apply exponent rule:

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

2^{7} \cdot 5 = 2^{6} \cdot 2 \cdot 5

= 2^{6} \cdot 2 \cdot 5

Apply radical rule:

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

2^{6} \cdot 2 \cdot 5 = 2^{6} 2 \cdot 5

= 2^{6} 2 \cdot 5

2^{6} = 8

= 8 2 \cdot 5

Multiply the numbers:

2 \cdot 5 = 10

= 810
