How would you define what a rational exponent is? How about rational expression?

Provide two rational expressions with different denominators for your classmate

to add or

subtract.

Hi Harry,

When we use the word "rational" in algebra we are referring to quantities that look like fractions (1/2, 1/x+4) or that can be made to look like fractions ( 2 2/3 = 8/3, 5 = 5/1). Therefore, a rational exponent is a fractional exponent and a rational expression is an expression that contains a fraction. When you add or subtract rational expressions with unlike denominators they could be numerical (1/2 + 2/3) or algebraic

(1/ x - 3/y).

I hope that this helps you.
