### What is the length and width of 21780 square feet?

There are an infinite number of answers to this question, as you can take any number greater than zero and less than 21780, divide it into 21780, and have a valid answer. You can express the relationship as: l = 21780 ft2 / w So if the width is half a foot, then the length would be 43560 feet. On the other hand, if the width is 180 feet, then it's length would be 121…

### What is the square root of -28?

the square root of -28 is the square root of -1 time the square root of 28. The square root of -1 is not a real number, it is represented by i. The square root of 28 is the square root of 4 times the square root of 7 (4*7=28) The square root 4 is equal to 2, and the square root of 7 cannot be simplified. The answer is 2iā7.

### Can the square root of x be added to the square root of 3x?

No. The Square root of x is not the value of x. So it can not be simplified beyond: Root X + root 3x Yes. The square root of 3x equals the square root of 3 times the square root of x, so when you add another square root of x, you can factor out the square root of x, thereby simplifying the expression to the square root of x times the sum of one…

### What is the square root of negative twenty?

Because the Square Root of negative 1 = i (The imaginary square root of negative 1.) and where if the square root of one number and of another number are multiplied together, the answer is equal to the square root of the two numbers combined. (Square root of 8 times the square root of 5 equals the square root of 40.) So... ā(-20) =ā20Ćā(-1) =ā4Ćā5Ći =2i(ā5) The answer is 2i times the square root of…

### What is the square root of 261?

The square root of 261 can be written as the square root of (9x29). Now the product rule for square roots tells us this is the same as square root of 9 multiplied by the square root of 29. This is 3xsquare root of 29. The square root of 29 can only be approximated. One approximation to square root of 261 is 16.1555.

### What is the square root of a negative number plus the square root of a negative number?

Nothing. You cannot have a square root of a negative number. The square root of negative one is called i, but i is an imaginary number. It does not exist and does not follow the properties of real numbers. (For example, if a and b are positive, then the square root of a times the square root of b is the square root of ab. But the square root of -7 is not the square…

### What is the conjugate of 5 square root of 10?

a+ square root of b has a conjugate a- square root of b and this is used rationalize the denominator when it contains a square root. If we want to multiply 5 x square root of 10 by something to get rid of the radical you can multiply it by square root of 10. But if we look at 5x( square root of 10 as ) 0+ 5x square root of 10 then the conjugate…
