Answer:

Step-by-step explanation:
Given:
The given expression is.

Now, we need to write the given expression in radical form.
Solution:
First, we can rewrite the term as:

Now, we can use this rule of exponents to rewrite the term again:


Now, we can use this rule to write the term as an radical:
![x^{\frac{1}{n}} = \sqrt[n]{x}](https://tex.z-dn.net/?f=x%5E%7B%5Cfrac%7B1%7D%7Bn%7D%7D%20%3D%20%5Csqrt%5Bn%5D%7Bx%7D)
![(x^{3})^{\frac{1}{2}} = \sqrt[2]{x^{3}}](https://tex.z-dn.net/?f=%28x%5E%7B3%7D%29%5E%7B%5Cfrac%7B1%7D%7B2%7D%7D%20%3D%20%5Csqrt%5B2%5D%7Bx%5E%7B3%7D%7D)

Therefore, the redical form of the given expression is 
Answer:
His teacher advised it because he did not have time to tutor Euler privately
Step-by-step explanation:
We know that
Euler in his autobiographical writings, talked about his tutor Johann Bernoulli. He claimed that his tutor was a very busy person who refused to give him private lessons, but gave him many valuable tips to start reading and studying more advanced math books on his own.
therefore
His teacher advised it because he did not have time to tutor Euler privately
