+14 and -14
The four possible answers are +/- 18 or +/- 22.
There are two possible answers because if you square a negative number, you will get a positive answer.
The square root of 4 * the square root of 81 four possible combinations:-2 * -9-2 * 92 * -92 * 9and two possible answers-2 * 9 and 2 * -9 = -18-2* -9 and 2 * 9 = 18
Well the simpler answers would be 1 x 224 = 224, or 2 x 112 = 224. If you are looking for the square root that square root button on the calculator will come as close as possible.
The square root of (five times five) is five. Since five times five is twenty five, the square root of that will be five. Also -5 is a possible answer for the square root. If the question is (square root of 5) times 5, then that's the same as square root of 125, which is approx 11.1803 and -11.1803
The square root of 18 is: ± 4.242641
square root 2 times square root 3 times square root 8
-9 and 5 are two possible answers.
You can always add radicals, but you can't simplify unless the radicands have a common factor. For example, the square root of 20 plus the square root of 45 equals 2 times the square root of 5 plus 3 times the square root of 5, which is 5 times the square root of 5.
Do the addition, get the answer and then find its square root!
The square root of 15 times the square root of 5 can be simplified as the square root of (15 * 5), which equals the square root of 75. The square root of 75 can be further simplified as 5 times the square root of 3. Therefore, the square root of 15 times the square root of 5 is equivalent to 5 times the square root of 3.
Square root of 2 times the square root of 46 = ±9.59166305
