What is the range of this function

Which expression is equivalent to7_/x^2 ÷ 5_/y^3? assume y# 0

Plz determine whether the polynomial is a difference of squares and if it is, factor it. y2 – 196 is a difference of squares: (y + 14)2 is a difference of squares: (y – 14)2 is a difference of squares: (y + 14)(y – 14) is not a difference of squares

M.xyz =radians. covert this radian measure to its equivalent measure in degrees.
