### What is the square root of 10X multiplied by the square root of 8X?

&radic;(10x) * &radic;(8x) = &radic;(80x&sup2;)&radic;(80x&sup2;) = &radic;(16x&sup2;) * &radic;(5) = 4x*&radic;(5)&#9632;

x = 8

### What is the square root of 10x Times Square root of 8x equals?

sqrt(10x)*sqrt(8x) = sqrt(80x2) = sqrt(16x2*5) = sqrt(16x2)*sqrt(5) = 4x*sqrt(5)

### X2 plus 8x-5 equals 0?

if you mean X&sup2;+8X-5=0: X1=-8/2 - Square root of ((8/2)&sup2;+5) X1=-4 - Square root of 21 X1 is about -8.58 X2=-8/2 + Square root of ((8/2)&sup2;+5) X2=-4 + Square root of 21 X2 is about 0.58

### What is the square root of x square plus 8x plus 15 equals 0?

x2 + 8x + 5 = 0 is an expression, not a value, and thus does not actually have a square root. If you are looking to solve for x, then you can say: x2 + 8x + 5 = 0 &there4; x2 + 8x + 16 = 11 &there4; (x + 4)2 = 11 &there4; x + 4 = &plusmn;&radic;11 &there4; x = 4 &plusmn;&radic;11

### What is the derivative of y equals square root of 8x plus square root of 4x?

y=(8x).5 + (4x).5 = (2+2sqrt(2))x.5 y'=(1 + sqrt(2))/sqrt(x)

### What is the square root of 4x-8x plus 9?

4x-8x = -4x &radic;-4x stands. However, x could not possibly be a positive number, because: (Negative) X (Positive) = (Negative) The square root of a negative number is undefined-so... (&radic;-4x) + 9 Is your answer.

### What number adds together to give -8 and multiple together to give 6?

Let's x be one of the numbers, and y the other number. So, x + y = -8 xy = 6 y = -x - 8 x(-x -8) = 6 -x^2 - 8x = 6 multiply by -1 both sides x^2 + 8x = -6 solve for x by completing the square; x^2 + 8x + 16 = -6 + 16 (x + 4)^2 = 10 x + 4 = square root of 10 x = -4 + square root of 10 or x = -4 - square root of 10 if we continue to solve the system of the equations, we can find the same value for y. Thus the numbers are -4 + square root of 10 and -4 - square root of 10. Check: (-4 + square root of 10) + (-4 - square root of 10) = -4 + square root of 10 - 4 - square root of 10 = -8 (-4 + square root of 10)(-4 - square root of 10) = (-4)^2 - (square root of 10)^2 = 16 - 10 = 6

### What is the sqare root of both sides 4x²-8x plus 4 equals 56?

The square root of the left hand side is 2*(x - 1).The square root of the right hand side is 2*sqrt(14)

### What is the square root of 8x squared plus 16 minus 3x equals 0?

the answer of &radic;8x+16-3x=0 is x= 0.447213595 = +/- 0.447(to 3 decimal places) if I'm not mistaken
