Question

Write $720$ as a product of the power of its prime factors? Also, write the index of the power of each prime number.

Answer 1

Prime factorization of $720$ is:

$\Rightarrow 720=2\times 2\times 2\times 2\times 3\times 3\times 5=2^4\times 3^2\times 5^1$

Hence, the indices of $2,3$ and $5$ are $4,2$ and $1$.
