Question

$729$ expressed as a power of $9$

Answer 1

If the same number is being multiplied multiple times, then it can be written in the form of base and power, base is the number that is multiplied multiple times and power is the number of times the number is multiplied. This type of representation is known as “Exponential form of a number”.

${\text{a×a×a×a×.......... n times = a}}^n$

Let's factorize $729$ –

$729=9\times 9\times 9=9^3$

Hence, $729$ is expressed as a power of $9is{9}^3.$
