It's a monomial and we are told to simplify and assume no denominator is equal to zero.
its a 10m1y0r means 10m to the neg. 1 power and y to the 0 power and r. I don't know how to write the powers. that equation is divided by 14m7y3r4.which means 14m to the 7 power y to the 3 power and r to the4 power.

What you have described should be written (in the typed format we have to use here) as
10*m^1* y^0 *r/[14*m^7*y^3*r^4]
Any number to the zero power is 1, so you can get rid of the y^0 term in the numnerator.
Exponents in the denominator can be brought to the numerator with a change of sign, and added to whatever exponent is in the numerator attached to the same variable. The 10/14 can be rewritten as the factor 5/7.
You are then left with
(5/7)m^7*y^3*r^5
