It is an irrational number a little less than 4. 15 = 16(1-1/16) Sqrt 15 = sqrt[16(1-1/16)] = 4[(1 - 1/16)^1/2} First, do a binomial expansion on: (1 - 1/16)^1/2 = 1 -1/32 + (1/2 X -1/2 X 1/256 X 1/2) + ----= 1 - 0.03125 - 0.000488 = 0.96826. So you just keep it as the square root of 15 It is not expressible as a rational number. Neither of those are a perfect square. The square root of 15 is irrational and cannot be represented exactly in any form other than sqrt(15). 3 and 5. 3sqrt10 Remember that sqrta*sqrtb=sqrt(a*b) sqrt15*sqrt6=sqrt(15*6) sqrt90 rarr This can be simplified further sqrt(9*10) rarr 9 is a perfect square and can be taken out of the radical 3sqrt10 Explanation: New questions in Spanish. Neither of those are a perfect square. Answer is 225 Let's have a different way for answering Nah we are not going to visit any online calculator. sophiadoglover sophiadoglover Answer: 3.87. There are a number of other ways you can compute a square root, including a second way due to Newton.. It is approximately equal to. Now multiply 0.96826 by 4 = 3.873 = sqrt 15. anyone wanna join my zoom me and my boy best friend are bored The square root of 15 is the square root of 15. We can find rational approximations 31/8, 244/63 15=3xx5 has no square factors, so sqrt(15) cannot be simplified. Add your answer and earn points. For the solution, we'll analyze the square root and search for a rational root. 1 and 15. Some common roots include the square root, where n = 2, and the cubed root, where n = 3. 3.8729833. which was computed using a calculator Because there are no factors that have a perfect square when multiplied together. [Except 1, but that puts you where you started.] In equation format: n √ a = b b n = a. Estimating a Root. In mathematics, the general root, or the n th root of a number a is another number b that when multiplied by itself n times, equals a. The square root of 15 is simply root 15, since neither 3 nor 5, 15's only factors, have square roots. What is the square root of 15 See answer hes to lazy to walk XD hey i created that one lol jordanbeighle84 is waiting for your help. The square root of 15 is not a rational number. sqrt(15) is not simplifiable. Calculating square roots and n th roots is fairly intensive.
