Answer 2

Answer:

The approximate value of

$\sqrt{780} = 28$

Step-by-step explanation:

We know that 780 lies between 400 and 900.

400<780<900

$20 < \sqrt{780} < 30$

we we know that between 20 and 30 we have ${27}^{2} = 729$and${28}^{2} = 784$

So,$729 < 780 < 784.$

As 784 is closer to 784 then 729, the approximate value of$\sqrt{780} \: is \: 28$
