Q: What is 3 times the square root of 4 minus two times the square root of 4?

Write your answer...

14

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.

The square root of two times the square root of two equals two

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.

5 times the square root of two over 3 times the square root of two equals 5/3

7.3

plus (+) 70 and minus (-) 70

X= plus or minus 1

No. For example, the square root of two plus (minus the square root of two) = 0, which is not an irrational number.

The numbers are: 6 plus square root of 27 and 6 minus square root of 27

Two times the square root of one hundred is twenty.

15 times the square root of two, all over two A formula is this: The diagonal for a square is always the sides of the square times the square root of 2

yes. Examples: the square root of 7 times the square root of 7 = 7 the square root of 7 times one over the square root of 7 = 1

X2+5x-6. a=1, b=5, and c=-6 The formula is: -b plus or minus the square root of b squared minus 4ac all over 2a. -b+square root of b2-4ac ---- 2a -5 plus or minus the square root of 5 squared minus 4(1)(-6) -5 plus or minus the square root of 25-4(-6) -5 plus or minus the square root of 25+24 -5 plus or minus the square root of 49 -5 plus or minus 7 Here is where you split into two different answers: Number 1: -5 plus 7= 2 Number 2: -5 minus 7= -12 Your answer is X=2, -12

I found the answer on Wolfram Alpha, input: ab = 208, a + b = 2. The answer is: 1 + 3i times square root of 23, and 1 minus 3i times square root of 23.

This doesn't factor neatly. Applying the quadratic equation, we find two imaginary solutions: Zero plus or minus 4i times the square root of 1x = 4i, -4iwhere i is the square root of -1.

Two times the square root of three plus five times the square root of three plus four times the square root of three equals eleven times the square root of three.

Two times the square root of 15 is the square root of 60. This is not a perfect square so we can only approximate it. It is about 7.75. Numbers such as 2 times the square root of 15 are known as irrational numbers since they cannot be written as a ratio or fraction.

Such that, rounded to two decimal places, the square root of 62 is equal to 7.87, the square root of -62 is equal to 7.87 i. ============================================================= You cannot have a square root for a negative number as the multiplication of any number with itself will ALWAYS give a positive number

No, it is just as well-defined as one, two, minus one, square root of two, i, etc.
