Question

estimate the square root of 250 to the nearest whole numbers​

Answer 1

Step-by-step explanation:

Square root of 97 to the nearest whole number is 10.

Square root of 250 to the nearest whole number is 16.

Square root of 780 to the nearest whole number is 30.

Step-by-step explanation:

A) \sqrt{97}

97

Group the digits into pairs

For digits to the left of the decimal point, pair them from right to left.

For digits after decimal point, pair them from left to right.

Now we have, 97

Refer the attached figure a for further steps

So, √97 = 9.848

So, Square root of 97 to the nearest whole number is 10.

B) \sqrt{250}

250

Group the digits into pairs

For digits to the left of the decimal point, pair them from right to left.

For digits after decimal point, pair them from left to right.

Now we have, 02 50

Refer the attached figure b for further steps

So, √250 = 15.811

So, Square root of 250 to the nearest whole number is 16.

C) \sqrt{780}

780

Group the digits into pairs

For digits to the left of the decimal point, pair them from right to left.

For digits after decimal point, pair them from left to right.

Now we have, 07 80

Refer the attached figure c for further steps

So, √780 = 27.928

So, Square root of 780 to the nearest whole number is 30.

Answer 2

Answer:

given √250

225<250<256

15^2<250<16^2

16^2 is closer to 250 more than 6

the estimated value to nearest whole number of 250 is 16
