The square root of 198 is between witch two numbers?

Work Shown:

Through trial and error, you should find that,

14^2 = 14*14 = 196

15^2 = 15*15 = 225

The value 198 is between 196 and 225. It is much closer to 196, than it is to 225.

So sqrt(198) is between 14 and 15. The value of sqrt(198) is much closer to 14 than it is to 15.

Using a calculator, we see

sqrt(198) = 14.07

which confirms our answers

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.
