hi im here again to help you with math problems with PRINCIPAL ROOTS AND IRRATIONAL NUMBER...

basically if you now how to multiply its gonna be easy to you.
exaple#1=what is the root of 7
7=7×7=48 but if you want to now how to get the square root the □root is 7 whatever number like -3 or 3. the 7 is the root . how to solve a problem like this 25
thats is equal to 5×5=25. all of the first number to multiply that is the square root only positive number like this 3 we can call PRINCIPAL ROOT not negative like this -2 . but if the given number is like this 9 3
_ = _
25 5 why is the answer is 3over5
because 3×3=9 and 5×5=25
thats why 3over5 is the answer



hope you learn something in this simple words bye.. ​
