Simplifying roots with exponents
WebbYou have probably heard of a square root, written √, but you can also take a third, fourth and even a 5,000th 5, 000 t h root (if you really had to). In this lesson we will learn how a square root is defined and then we will build on that to form an understanding of n th roots. We will use factoring and rules for exponents to simplify ... WebbOnly if you are taking the principle root and you are SIMPLIFYING the radical can you put in the absolute value. If he would have put the absolute value sign for the x under the …

WebbThe alternate way is to go into rational exponents so if you have the cube root of the square root of (x-5) =2, you get ((x-5)^(1/2))^1/3 = 2, power to power requires multiplication, so (x-5)^1/6 = 2, opposite of 1/6 is 6 in exponent, so (x-5)^(1/6*6)=2^6, x-5=64, x=69. So one of the questions in the foundations part lists y to the 9th.
