As both the numbers 8 and 6 are divisible by 2 on solving we get. Here's an example: j2 = -1. Because of the fundamental theorem of algebra, you will always have two different square roots for a given number. 6) The bases are both 3, so the exponents are equal #a + 1 = 3# 7) Subtract 1 from both sides to isolate #a# #a = 2 larr# answer. If a radical is fully simplified, there is no factor of the radicand that can be written as a power greater than or equal to the index, there are no fractions under the radical sign, and there are no radicals in the denominator. I have solved the problem in the above photo and also given the explanation why the given polynomial is not equal to â-2â. hope you get it To rationalize the denominator multiply the fraction by the appropriate form of, https://socratic.org/questions/how-do-you-rationalize-the-denominator-and-simplify-sqrt6-sqrt5-sqrt3, https://socratic.org/questions/how-do-you-rationalize-the-denominator-and-simplify-2sqrt-2-2sqrt-3-sqrt3, Multiply both top and bottom of the fraction by, 4\times \left(\frac{\sqrt{5}\left(\sqrt{5}+\sqrt{2}\right)}{\left(\sqrt{5}-\sqrt{2}\right)\left(\sqrt{5}+\sqrt{2}\right)}\right).
