The square source of a number n can be composed as √n. It way that there is a number aa such that a×a=n. This can additionally be written as, a2=n ⇒ a=√n. So, a is same to the square source of n.Now, if n=89, then a=√89 is the square source of 89. In the radical form, the square root of 89 can be stood for by √89. The square source of 89 = 9.43 in the decimal kind up to 2 decimal places. A rational number is a number that can be express in the kind of p/q. A number the is not a reasonable number is dubbed an irrational number. Due to the nature the its non-repeating and non-terminating decimal expansion, the square root of 89 can not be composed in the form of p/q, hence, the is an irrational number.The worth of the square source of 89 in decimal form is 9.433981.. For this reason on, The square root of a number can have two values, a positive and also a an adverse value. So, √89=+9.433981. Hence, The square root of 89 is an irrational number with never-ending digits.

The long division method helps united state to uncover a more accurate worth of the square root of a number. Let"s see the steps to uncover the square source of 89 by the long department method.

Step 1: Divide the number 89 by 9, (because 92 =81 is a perfect square number simply less than 89).Step 2: The divisor and also the quotient have to be the exact same numbers; in this case, it is 9. Main point the quotient and also the divisor and subtract the result from 89.Step 3: For the following divisor, add the vault divisor with the quotient. (9 + 9 = 18); place it together the brand-new divisor v a blank on that is right.Step 4: Put a decimal after quotient "9" and bring down 2 zeros to location it after ~ 8 so the it i do not care 800. (184 × 4 = 736). Subtract 736 from 800.(800 − 736 = 64)Step 5: Bring down one more pair that zeros and place the after 64, so the it i do not care 6400. Take the new quotient 4 and include it come 184. (184 + 4 = 188)Step 6: Repeating the above steps, we must fill the blank with a number together that as soon as the brand-new divisor is multiplied with the brand-new quotient, the product is much less than or same to the dividend 6400. (1883 × 3 = 5649)Step 7: write the same number after ~ 4 in the quotient. Subtract 5649 from 6400. (6400 − 5649 = 751)Step 8: Repeat the process until we acquire the remainder same to zero. The square root of 89 up to two areas is obtained as 9.43 through the long division method. Explore Square roots utilizing illustrations and interactive examples

Use the hit and trial method while calculating the square root of any number.The square source of a number have the right to have 2 values.The square source of any kind of number can be assumed in between the square root of two nearest perfect squares of that number. For example, the square source of 89 lies between the square source of 81 and 100. So worth would be better than 9 and less 보다 10.
Find the square source of 899 by the approximation method.Find the largest 5-digit number i m sorry is a perfect square.

Example 1 Kevin desires to repaint the rectangle-shaped floor the his garage. The length of the floor is 10 feet and the width is √89 feet. Deserve to you assist him discover the area that the floor that he needs to paint?

Solution Given: Length that the rectangle floor = 10 feet and also width of the rectangle floor = √89 feetArea of the floor = Length×WidthArea =10×√89 =10×9.43Area=94.3 feet2

Example 2 Help Tim evaluating √89 × √89.

Solution:

We understand that √89 = 9.43399.7339 × 9.4339 = 88.99 ≈ 89on multiplying √89 by √89 we get 89.
