** The square root of a negative will often give you an error (what can you square to get a negative, since any number squared is positive?), but on certain calculators it gives a complex number (actually two complex numbers). These are not real numbers; for the purposes of this course there is no real square root of a negative number.

There is no real number that can be squared to give a negative. If you square a negative number you get a negative times a negative, which is positive. If you square a positive number you get a positive number. So a negative number has no real square root. **

Query 1.4.42 drawer has 18 compartments; how many drawers to hold 204 tapes?

......!!!!!!!!...................................

RESPONSE -->

204/18=11.34 So we would need 12 drawers with 18 compartments becuase if you only have 11 drawers you would not have enough space for the tapes so you would need another drawer to accommodate all the tapes.

** 204 / 18 = 11 with remainder 6. If we had 11 drawers they would hold all but 6 of the tapes.

The leftover tapes also have to go into a drawer, so we need a 12th drawer. **

RESPONSE -->

It is better to have to much than not enough.
