18+567/9. The square root is over the 567 and the 18 and 567 are written as a fraction over 9
:
Assume you mean:
:
%2818%2BSqRt%28567%29%29%2F9
:
Find the highest square you can factor out of 567, it will be 81. you can write it:
:
%2818%2BSqRt%2881%2A7%29%29%2F9
:
:
Extract the square root of 81 and you have:
:
%2818+%2B+9%2ASqRt%287%29%29%2F9
:
:
notice that you can divide 9 evenly into 18 and 9 leaving you with:
:
2 + SqRt(7)
