Question

What is an estimate for the square root of -93

Answer 1

approximately 9.64

Explanation:

The square root of 93 is approximately 9.64.

Answer 2

• 9.3 or 9.4

Explanation:

We need to estimate √93.

Use formula below:

• 
  `√(x^2+y) =x +(x/2y)`

or

• 
  `√(x^2-y) =x -(x/2y)`

In the given case the formula works as:

• 
  `√(93) =√(9^2+12) =9+(9/2*12) = 9+(9/24)=9.4`

or

• 
  `√(93)=√(10^2-7) =10-(10/2*7)=10 - 5/7 = 9.3`
