4] Which perfect square root is close to ?
Well we know that 7 times 7 is 49, and 6 times 6 is 36, so our answer will be between and
The closer root is , so we can approximate that the square root of 39 is around <u><em>6.2</em></u>.
5] We can do a similar step-by-step here.
4 times 4 is 16, and 5 times 5 is 20.
This gives us and
Well, they are both equal distance from (2), so we can do this:
We know it'll be between 4 and 5 (the number plot in the answer lets us know that too)
4 times 4 is 16
4.1 times 4.1 is around 16.8
4.2 times 4.2 is about 17.64
4.3 times 4.3 is 18.49
Now that we have an 18, we can stop going and see which one is closer.
18 - 18.49 = -0.49
18 - 17.64 = 0.36
4.2 times 4.2 is closer, so we can approzimate that is around 4.2
