Given Solution: `a** The meaning is 1^2, 1^3, 1^4. We take a power of the base. The result is always 1. ** &&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&& Self-critique (if necessary):ok ------------------------------------------------ Self-critique Rating:ok ********************************************* Question: `qQuery (previously 1.4.30) What can you say about the square root of a negative number? What can you say about the square of a negative number? YYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY Your solution: Since no real number can be squared and give you a negative number, most calculators will give an error. If you square a negative number you are multiplying a negative number by the same negative number which gives you a positive number. also if you square a positive number you are multiplying a positive number by the same positive number and still get a positive number. Negative numbers have no real square root. confidence rating #$&*: 3 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
.............................................
Given Solution: `a** The square root of a negative will often give you an error (what can you square to get a negative, since any number squared is positive?), but on certain calculators it gives a complex number (actually two complex numbers). These are not real numbers; for the purposes of this course there is no real square root of a negative number. There is no real number that can be squared to give a negative. If you square a negative number you get a negative times a negative, which is positive. If you square a positive number you get a positive number. So a negative number has no real square root. ** &&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&& Self-critique (if necessary):ok ------------------------------------------------ Self-critique Rating:ok ********************************************* Question: `qQuery 1.4.38 (previously 1.4.42) drawer has 18 compartments; how many drawers to hold 204 tapes? YYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY Your solution: 204/11.333 we would need to round up to the next whole number since we still have to put the remaining tapes into a compartment also. so you would need 12 compartments confidence rating #$&*: 3 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
.............................................
Given Solution: `a** 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. ** " Self-critique (if necessary): ------------------------------------------------ Self-critique rating: ********************************************* Question: `qQuery 1.4.38 (previously 1.4.42) drawer has 18 compartments; how many drawers to hold 204 tapes?
