how do you do a square root in MIPS? I have to write a program to find the hypotenuse of a right triangle and I'm stuck on this part. Please help.

> how do you do a square root in MIPS?
Same as anywhere else, assuming you lack a library to do it
- research algorithms (you've got google, do some searches)
- write code
- test code

If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.

Are there more restrictions on the answer that you're not telling us?
What does "split the number by 2" mean anyway - divide?

not divide by 2 but separate the digits into 2.
example: if the number I want to root is 96358
9, 63, 58 is what i split it into.

I can't help you any more without giving you the answer on a plate.

What were the rules your teacher gave you?
Which flavor of MIPS are you using?
There are scalar and vector square root functions and estimated reciprocal square root vector functions, dependent upon which MIPS family chipset you're using!
There are also algorithmic guesstimation formulas for integer only processors.
