Alright;
Solving without the help of calculator will be as follows;
that is you find a common factor for both terms, here it is 5. (5*16=80 and 5*9=45).
So we continue as follows;

that is and
since the equation has two identical square root of 5, we can therefore add them together, which will give
Hence, the solution of in a radical form is .
