Answer 1

Square root of 780 to the nearest whole number is 30. For digits to the left of the decimal point, pair them from right to left.

Answer 2

Step-by-step explanation:

we know that 780 lies between 400 and 900

400 < 780 < 900

$20 < \sqrt{780} < 900$

we know that between 20 and 30 we have

${27}^{2} = 729$and ${28}^{2} = 784$

so, 729 < 780 < 784 . S7 it is closer to 78410 729 the approximate value of $\sqrt{780}$ is 28
