Four of anything minus one of the same thing always leaves three of them.
The square root of any negative number is equal to the square root of its absolute value followed by i - an imaginary number representing the square root of minus one. Therefore, such that sqrt(25) = 5, sqrt(-25) = 5i.
It is +1
The square root of negative one is an imaginary number, signified by the italic lower-case i.
[ 2 minus square root of 5 ] is the only one.
Negative square root is -√Square root of negative one is i.
I, the square root of -1
Rounded to two decimal places, sqrt(-2272) = 47.67 i. i is an imaginary number equal to the square root of minus one, and thus 47.67 i is equal to 47.67 times the square root of minus 1.
If this is supposed to be a riddle, it's not a very good one. The square root of the number whose square root is two is, obviously, two.
X= plus or minus 1
It has to be a stupid answer anyway
if x^2 = 49, then the square root property says you can take the square root of both sides as long as you make one a plus-minus. x^2 = 49, which means square root of x^2 = plus minus the square root of 49 the square root of 49 is 7, so +- 7. We get: x = plus/minus 7 (this means either positive 7 or negative 7)
Such that the square root of 363 is equal to 19.05256 (rounded to five decimal places), the square root of -363 is euqal to 19.05256 i. The lower-case letter i represents the square root of minus one, an imaginary number.
This one's ugly.(5 times the square root of 23 minus 4it)(5 times the square root of 23 plus 4it)where i is the square root of negative one.
still 1The square root of 1 is plus or minus 1. √1 = ± 1 The reason is that 12 = 1 and -12 = 1. (Either 1 squared or minus 1 squared equals one.)
No, it is just as well-defined as one, two, minus one, square root of two, i, etc.
Pick up any calculator - or use the one included in Windows or whatever operating system you use - and calculate the square root of 63.This will give you a positive number; the same number with a minus sign will also work.
Example: The square root of 54 The square root of 54 is not an integer, since 54 is not a perfect square. The square root of 54 will be between 7 and 8, since 54 is between 49 and 64. Since 54 is closer to 49 than it is to 64, the square root will be closer to 7 than 8. I'd estimate the square root of 54 to be approximately 7.35 The actual square root is plus or minus 7.3484692 To simplify a square root, search for any factors greater than one that are perfect squares. Since 54 = 9 x 6, the square root of 54 equals the square root of 9 x 6 equals the square root of 9 times the square root of 6. The square root of 9 is 3, so the square root of 54 simplified is 3 times the square root of 6.
In one bracket, write 16 times the square root of 2 minus 3x. In the other one, write 16 times the square root of 2 plus 3x.
The derivative, with respect to x, is -x/sqrt(1-x2)
To take the square root of any power, just reduce the exponent to one-half of each value.
The square root of one is one.
If a is any number, then a squared = (-a) squared, so one might say that a and -a are both square roots of a squared. However, the square root symbol always means the positive square root.
