Answer:
125
Step-by-step explanation:
since you take away 2/5 of the original number to get 75, 75 is equal to 3/5's of the original. You then divide 75 by 3, get 25, then multiply 25 by 5 to find the answer which is 125.
About 176.4 is what i had gotten but i would still check out the other persons answer and compare
I think the answer is br/b-r = a
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
