Exponent 1 n When n Is Even If n is a positive even integer and a is a positive real number, then a 1 n de- notes the positive real nth root of a and is called the principal nth root of a. An exponent of n indicates nth power, an exponent of n indicates the reciprocal of the...

Rational exponents can be expressed as radicals, that is, am/n=n√am. For example, we can write the square root of 5 as a rational exponent as well as in radical form: √5 = 51/2 What are Positive Rational Exponents? Positive rational exponents are expressed with positive exponents. For...
2. Students will know and be able to evaluate expressions with rational exponents. A rational exponent does not have to be of the form 1/n. Other rational numbers such as 3/2 can also be used as exponents. You can use the properties of exponents to evaluate or simplify expressions involvi...
A rational exponent can always be turned into a radical. If b to the nth root of a number is real, and m is a positive integer, then rational exponents and radicals are related like this: b1n=n√bandbmn=n√bm=(n√b)m The denominator of the fraction is the value of the root. Fo...

What is a rational (or fractional) exponent? A rational (that is, a fractional) exponent is a power that is expressed as a fraction, and which represents a radical. For instance, the expression 813831 means "the cube root of eight", or 8 338, which is 2. MathHelp.com Rational...
