Problem 27E

How can you write any real power of x as a power of e? Are there any restrictions on x? How does this lead to the Power Rule for differentiating arbitrary real powers?

Step-by-Step Solution:

Solution:-

Step 1 of 3</p>

Given that

We have to explain how can we write any real power of  as a power of e? Are there any restrictions on x? How does this lead to the Power Rule for differentiating arbitrary real powers?

Step 2 of 3</p>

We have to take any real power of  say

Suppose

This can be written as power of  as

=

Therefore, we can write any real power of  as a power of e as .

Yes,there are  restrictions on

Here, restriction on  is

Step 3 of 3
