The square source of a number means a number whose product with itself gives the initial number.The square source of 42 is 6.4807.The square source of 42 is composed as √42 in radical kind and it can not be reduced further.The square source of 42 deserve to be written as (42)1/2 in exponential form.

A reasonable number is a number that deserve to be express in the type of p/q whereby q ≠ 0.And the square root of 42 cannot be expressed in the type of p/q.So, the square source of 42 is an irrational number.

We will now calculate the square root of 42 utilizing these methods:

### Square root of 42 utilizing Approximation Method

Find 2 consecutive perfect squares between which the number 42 lies. The 2 numbers are 36 (62) and also 49 (72).So, the entirety number part of the square source of 42 will be 6.Now, for the decimal component we will use the formula:(Given number - Smaller perfect square) / (Greater perfect square - smaller perfect square)= (42 - 36)/(49 - 36) = 6/13 = 0.461So, the approximated square root of 42 through the approximation an approach is 6.461.

### Square source of 42 by lengthy Division

Now we will calculate the square source of 42 by the long department method.

Start pairing the digits from the appropriate side by placing a bar on optimal of them. In this case, us only have one pair (42).Now uncover a number(z) such the z × z ≤ 42. So, z will certainly be 6 together 6 × 6 = 36 ≤ 42.Bring under one pair of zero. Hence, ours dividend becomes 600. Uncover a number(m) such the 12m × m ≤ 600. The number m will be 4 as 124 × 4 = 496 ≤ 600.Now repeat the above step for the continuing to be two pairs of zeros. So, we get the square source of √42 = 6.480 by the long division method.
