Solution steps

756

Prime factorization of

756 : 2^{2} \cdot 3^{3} \cdot 7

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

Apply exponent rule:

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

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

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

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

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

Apply radical rule:

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

2^{2} = 2

= 2 3^{2} 3 \cdot 7

Apply radical rule:

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

3^{2} = 3

= 2 \cdot 3 3 \cdot 7

Multiply the numbers:

2 \cdot 3 = 6

= 6 3 \cdot 7

Multiply the numbers:

3 \cdot 7 = 21

= 621
