Hi,

root%282%2C-98%29%2Aroot%282%2C-50%29+=+root%282%2C-98%2A-50%29=+root%282%2C4900%29=+70+ 



See following Rules for Exponents:



a%5E0+=+1

%28a%5Ep%29%5Eq+=+a%5E%28p%2Aq%29

root%28a%2Cp%29%2Aroot%28a%2Cq%29+=+root%28a%2Cp%2Aq%29  |For example: root%282%2Cp%29%2Aroot%282%2Cq%29+=+root%282%2Cp%2Aq%29 

x%5Em%2Fx%5En=x%5E%28m-n%29

%28+x%5Em+%29%28+x%5En+%29+=+x%5E%28+m+%2B+n+%29
