I am 13 years old. I would like to solve more & more problems related to the topic exponents & radicals like the ones given in the URLs 1. Integral Exponents (Example 4, Exercises Question 2 & 3) & 2. Fractional Exponents (Example 3). I have been searching the net to get such problems but am not able to find such problems (the problems I have come across are far too easy).
Can someone please suggest me some websites wherein I can find such problems on exponents & radicals?
