Question

Approximate the following irrational numbers to the nearest whole number. $negative square root of 39$

hint Hint:

Hint:
For rounding off a number to the nearest whole number, we have to look at the first digit after the decimal point. If this digit is less than 5 i.e. 1, 2, 3 or 4 then we don’t have to do anything, but if the digit is 5 or greater i.e 5, 6, 7, 8, 9 we must round up. For example, the nearest whole number to the number 2.8 is 3 while in the case of 2.45, it will be 2.

The correct answer is: -6

Let’s say x = $negative square root of 39$
$negative square root of 39$ is an irrational number and its approximate value is 6.244997….
x = - 6.244997…
As the digit after the decimal point is 2 which is less than 5. So, the nearest whole number will be - 6.
Final Answer:
Hence, the nearest whole number of $negative square root of 39$ is - 6.
