Express each of the following numbers in exponential form:
(1) 125 (2)243 (3)288

Given:

Given numbers are:

(1) 125 (2)243 (3)288

To do:

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

Solution:

(1) 125

Prime factorisation of 125 is,

$125=5\times5\times5$

$=5^3$.  

(2) 243

$243=3\times3\times3\times3\times3$

$=3^5$.

(3) 288

$288=2\times2\times2\times2\times2\times3\times3$

$=2^5\times3^2$.
