Estimate the value of the 80 to the nearest whole number

First we will find the values of squares in between 80 lies. The value of 8 2 is equal to 64 and the value of 9 2 is equal to 81 . And, we can see that, 80 lies in between 64 and 81 . Thus, 64 < 80 < 81 or 8 2 < 81 < 9 2 . Now, we will calculate the difference of 64 and 80 ⇒ 80 - 64 = 16 And, the difference of 80 and 81 is; 81 - 80 = 1 We can see that one of the difference is 16 whereas another is 1 . Therefore, the square root of 80 is nearest to the integer 9 . Hence, the estimated value of 80 to the nearest whole number is 9 .

Estimate the value of the 1000 to the nearest whole number.

First we will find the values of squares in between 1000 lies. The value of 31 2 is equal to 961 and the value of 32 2 is equal to 1024 . And, we can see that, 1000 lies in between 961 and 1024 . Thus, 961 < 1000 < 1024 or 31 2 < 1000 < 32 2 . Now, we will calculate the difference of 961 and 1000 ⇒ 1000 - 961 = 39 And, the difference of 1000 and 1024 is; ⇒ 1024 - 1000 = 24 We can see that one of the difference is 39 where as another is 24 . Therefore, the square root of 1000 is nearest to the whole number 32 . Hence, the estimated value of 1000 to the nearest whole number is 32 .

Estimate the value of the 350 to the nearest whole number

First we will find the values of squares in between 350 lies. The value of 18 2 is equal to 324 and the value of 19 2 is equal to 361 . And, we can see that, 350 lies in between 324 and 361 . Thus, 324 < 350 < 361 or 18 2 < 350 < 19 2 . Now, we will calculate the difference of 324 and 350 ⇒ 350 - 324 = 26 And, the difference of 350 and 361 is; 361 - 350 = 11 We can see that one of the difference is 26 whereas another is 11 . Therefore, the square root of 350 is nearest to the integer 19 . Hence, the estimated value of 350 to the nearest whole number is 19 .

Estimate the value of the 500 to the nearest whole number

First we will find the values of squares in between 500 lies. The value of 22 2 is equal to 484 and the value of 23 2 is equal to 529 . And, we can see that, 500 lies in between 484 and 529 . Thus, 484 < 500 < 529 or 22 2 < 500 < 23 2 . Now, we will calculate the difference of 484 and 500 ⇒ 500 - 484 = 16 And, the difference of 500 and 529 is; 529 - 500 = 29 We can see that one of the difference is 29 whereas another is 16 . Therefore, the square root of 500 is nearest to the integer 22 . Hence, the estimated value of 500 to the nearest whole number is 22 .
