simplify or solve if it is an equation: i keep asking question but some of the tutors keep asking me if it is a variable or something but the instructions just say simplify or solve if it is an equation.
4) SR(27) =
5) SR(12x7) =
-----------------
Is SR square root? If so,
4) SR(27)
sqrt%2827%29+=+3sqrt%283%29
-------------
5) SR(12x7)
sqrt%2812%2A7%29+=+sqrt%2884%29
=2sqrt%2821%29

If SR is not square root, you'll have to find out what it is.
If it is square root, you should have said so.
If it is square root and you didn't know that, you should have found out.
