If you learn the rules for exponents and radicals, then your enjoyment of mathematics will surely increase! In the following, n;m;k;j are arbitrary -. PLAY. Polynomials. Radical expressions are always represented using a radical symbol ( √ ), while exponents don’t involve any symbolic representation. Express each of the following as a product of powers of primes, i.e, in exponential form: (i) 429 (ii) 648 (iii) 1512 2. Exponential Notation an = a * a * a * a…* a (where there are … index the number above the radical sign indicating the nth root. When using this method to simplify roots, we need to remember that raising a power to a power multiplies the exponents. For example when we raise 2 by 2 we get 4 but taking square root of 4 we get 2. For example, a cube root is equivalent to an exponent of 1/3; a fourth root is an exponent of 1/4. Important rules to simplify radical expressions and expressions with exponents are presented along with examples. Example 14 2 4√4 √3 . The denominator is rationalized. If you combine a radical with an integer exponent then you can express the same concept as a rational exponent. View S-1.2 Exponents and Radicals.pdf from MATH 19500 at The City College of New York, CUNY. The index must be a positive integer. When we use rational exponents, we can apply the properties of exponents to simplify expressions. a⁶*b³, since we have different bases and thus can't simplify any further. Rules for Exponents.
