If you have more than 1 number after the decimal, keep moving the decimal until the number is whole. We still have yet to cover dividing radicals, rationalizing the denominator, and converting between radical form and rational exponent form. There is a more efficient way to find the ℎ root by using the exponent rule but first let’s learn a different method of prime factorization to factor a large number to help us break down a large number into primes. The expression is called a radical expression. You only need to know how to divide and rationalize for radicals with an index of 2. Example 1: … D.
