Express each of the following numbers in exponential form:

(1) 512 (2)625 (3)729


Given:


Given numbers are:

(1) 512 (2)625 (3)729

To do:


We have to express each of the given numbers in exponential form.

Solution:


(1) 512

Prime factorisation of 512 is,

$512=2\times2\times2\times2\times2\times2\times2\times2\times2$

 

       $=2^9$.

(2) 625

$625=5\times5\times5\times5$

       $=5^4$.

(3) 729

$729=3\times3\times3\times3\times3\times3$

       $=3^6$.
