what is the positive square root of 25?
Answer
Explanation:
Step1: Recall square - root concept
The positive square root of a number (x), denoted as (\sqrt{x}), is a non - negative number (y) such that (y^2=x). For (x = 257), we want to find (y=\sqrt{257}). Since (257) is a prime number, we can approximate its value. We know that (16^2=256) and (17^2 = 289). Using a calculator, (\sqrt{257}\approx16.031)
Answer:
( \sqrt{257}\approx16.031)
