In order to rewrite with rational exponents, it helps to know the definition of any rational exponent, namely: If q and p are integers, q does not equal zero and b is a real, positive number, then bp/q equals (^q√b)p equals ^q√bp. The definition of b1/4 is ^4√b, because (b1/4)4 equals b.
Therefore, to rewrite with a rational exponent, the expression ^4√18 can be rewritten as 18(1/4), or 181/4.

In chapter five, linear systems are solved, while factoring, exponents and polynomials are the subject of chapter six. Chapter seven is dedicated to rational expressions and equations. The subjects touched on above, namely radical expressions and equations are expanded on in chapter eight.
Relations and functions are discussed in chapter nine, quadratic equations in chapter 10 and statistics in chapter eleven. Geometry has a place in chapter 12, while discrete mathematics and probability can be found in chapter 13. This is just the line-up in the Algebra 1 section, more help can be located on their home page.
