WebA square root just gives a number that when multiplied with itself gives the number the square root is being found of. Like √4 = 2 As 4= 2*2 Let's take x^1/2 * x^1/2. The product rule of exponents is : x^a * x^b = x^(a + b) So by this x^1/2 * x^1/2 = x^( 1/2+1/2)= x^1 = x Also now what is the square root of x ? WebA function defined by y = log a x, x > 0, where x = a y, a > 0, a ≠ 1 is called the logarithm of x to the base a. The common logarithmic function is written as y = log 10 x. We shall …
