How to take out underoot value

1.	How to take out underoot value
Answer» You can take user root value as follows:For example;If, the given value is 1÷√3You can multiple denominator as shown in below=1÷√3×√3÷√3=√3×√3=3So the answer is √3÷3 We can find under roots by the prime factorisation methodLet\'s take an example-- √400 (under root 400)Step 1-- break it into it\'s prime numbers. (√16 × √25)Step 2-- here we can see the exact two no. Which are the exact root of 4 and 5. (√16=4 and √25=5)Step 3-- now multiply the two no. With each other. And we get the answer.(4×5=20)The other method to find the under root of √400 isStep 1-- break it into it\'s prime factors. (√2×2×2×2×5×5)Step 2-- now we can take the pairs outside of the root. (2×2×5)Step 3 -- now multiply the no. With each other. And we get the answer. (4×5= 20)
