Question

Write each of the following in Exponential form :-

$19\times a\times a\times a.......9times\times b\times b\times b\times .....11times$

Answer 1

Exponential form :- The exponential form is an easier way of writing repeated multiplication involving base and exponents.

For example, we can write 5 × 5 × 5 × 5 as 5⁴ in the exponential form, where 5 is the base and 4 is the power.

In this form, the power represents the number of times we are multiplying the base by itself.

Here, in this given question $19\times a\times a\times a......9times\times b\times b\times b......11times=19a^9{b}^{11}$.

As here $a$ is multiplied $9times$ and $b$is multiplied $11times.$

So, $aandbarethebases$and $9and11arethepowers.$
