Answer 1

Answer:

What should be subtracted from 18,246 to get the perfect square number?

You could use a calculator to find what the square root of 18,246 is to see what number to be squared. The take the difference between this square number and 18,246 and you have the answer.

Of course, you could also list square numbers close to 18,246 and work your way from there.

You can start with 10,000, since 100^2 = 10,000. As 200^2 = 40,000, you know the square you want, is roughly in the middle between the two. (by the way 150^2 = 100 * 200 + 50^2 = 22500, so your number is a little less than 150.)

I leave the actual calculation with you.

Using Excel makes this job a breeze, by the way.
