The square root of (-5)2 is 5. (-5 is also a square root, but "the" square root refers to the positive root in this case.) The square root of -52 is the square root of -25, or 5i. "i" is the imaginary unit. Read about "imaginary numbers" or "complex numbers" for more information. This would create confusions. Would that mean that the square of any negative number is negative?

The square root of 5 squared is 5, which is a rational number.

b over the square root of 5 The square root of 5b squared is 5b, and the simplified form of the square root of 125 is 5 root 5. The 5s then cancel out leaving b over the square root of 5.

No, it is not even a real number. The square root of negative 5 is the square root of 5, times i.

square root(-5) = 2.23606798 i

A negative square root is an imaginary number.

It seems to be 25. Call your number "x". x = 5 square root of (5 square root of (5 ...) Square it; this will eliminate the outermost square root sign: x squared = 25 times 5 square root of (5 square root of (... Dividing the second equation by the first one, you get: x squared / x = 25 x / x x = 25

a square root is the opposite of a square.5 squared is 5 x 5 so 25that means that the square root of 25 is 522 = 4square root of 4 = 2

From point A to point B You need the X and Y value of both point A and B Formula = Distance = Square root of [(x1 + x2)2 + (y1 + y2)2] So therefore given points (1:2) and (5:-6) Square root of (1 - 5)squared + (2 + 6)squared =Square root of -4 squared + 8 squared =Square root of 16 + 64 =Square root of 80 This can be your answer but you should go a step further =Square root of 80 =Square root of 16 * 5 =4*Square root of 5

5 squared is 25 4 squared is 16 25-16= 9 the square root of 9 is 3.

Restricting the discussion to real numbers for now. In this case, the square root is only defined for non-negative numbers; the principal square root of a positive number is the POSITIVE square root. For example, both +5 and -5 are square roots of 25, since both - when squared - give you 25. But the positive square root (+5) is called the principal square root, and if you write the square root symbol, that's the number usually meant.

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... √(-20) =√20×√(-1) =√4×√5×i =2i(√5) The answer is 2i times the square root of 5. square root (-20) = square root (-1) x square root (20) square root (-20) = i x 4.47213595 square root (-20) = 4.47213595 i

The square root of 5 is closer to 2. 2 squared is 4 and 3 squared is 9. 4 is much closer to 5 than 9.

There is no answer - 5 * -5 is 25 as a negative times a negative is a positive and - - 5 * 5 is - 25 but you cannot do this inversely if you put square root - 25 it says undefined

In increasing order, they arenegative 31 over 6negative square root 26negative 5negative 5 over 6

- (400^.5) = -(20) = -20 you just do the square root of the number, and attach the negative in front. and if you ever include the negative inside the square root, you'd have to deal with i, which is an imaginary number that signifies the square root of negative 1.

square root of 80 simplified= 16*5= 4 squared *5

2(q^2 - 5) or 2(q - the square root of 5)(q + the square root of 5)

It depends on whether you take the positive square root of 4 (YES) or the negative square root of 4 (No).

well, the square root of 81 is 9, and seven squared is 49, so it wud be 40

b is the square root of 5/3
