**Important Notes: **

The square source of 18 is stood for as √18 in radical form.The square source of 18 is stood for as (18)1/2 in exponential form.

**Challenging Questions:**

Find the value of √√18?Jake initially planned to do a square-shaped pool of area 20 square feet but was only able to make a pool v an area that 18 square feet. Through how numerous feet the next of the swimming pool is quick than what was at first planned?

**Example 1:** uncover the square source of 18 utilizing the approximation method?

**Solution:**For calculating the square root of 18 via the approximation method very first we require to find two perfect squares in between which 18 lies.We understand that 16 and 25 space the 2 perfect squares in between which 18 lies. So, the square source of 18 will be higher than 4 however less 보다 5. Therefore, the entirety number part will it is in 4.Now because that the decimal part, we will use the formula:

Given number- reduced perfect square / bigger perfect square-Lower perfect square= (18-16)/(25-16)= 2/9= 0.22So, the approx. The square root of 18 will be 4.22

**Example 2:** Kevin desires to calculation the square source of 7/18. Have the right to you assist Kevin?

**Solution:**Square source of 7 = √7Square root of 18 = 3√2Hence, Square root of 7/18 = √7/(3√2) = 3√(7/2)
