Answer 2

Answer:

• 9.3 or 9.4

Step-by-step explanation:

We need to estimate √93.

Use formula below:

• $\sqrt{x^2+y} =x +(x/2y)$

or

• $\sqrt{x^2-y} =x -(x/2y)$

In the given case the formula works as:

• $\sqrt{93} =\sqrt{9^2+12} =9+(9/2*12) = 9+(9/24)=9.4$

or

• $\sqrt{93}=\sqrt{10^2-7} =10-(10/2*7)=10 - 5/7 = 9.3$
