Determine the first four numbers of N if N is <img src="https://tex.z-dn.net/?f=N%20%3D%20%20%5Csqrt%7B122436486072...2400%7D

Answer:

1106 . . . or
3499

see below for explanation

Step-by-step explanation:

The first four digits of the root depend on whether the exponent in scientific notation is even or odd.

If it is even, then the mantissa of the root is ...

$N \approx\sqrt{1.2243648607}\approx 1.106\dots$

If it is odd, then the mantissa of the root is ...

$N \approx\sqrt{12.243648607}\approx 3.499\dots$

Solve the following equation. Show all your work.

horrorfan [7]

$\dfrac{x}{x - 2} + \dfrac{x - 1}{x + 1} = -1$

$(x - 2)(x + 1) \times \dfrac{x}{x - 2} + (x - 2)(x + 1) \times \dfrac{x - 1}{x + 1} = -1(x - 2)(x + 1)$

$(x + 1)x + (x - 2)(x - 1) = -1(x - 2)(x + 1)$

$x^2 + x + x^2 - 3x + 2 = -x^2 + x + 2$

$3x^2 - 3x = 0$

$3x(x - 1) = 0$

$x = 0~~~or~~~x - 1 = 0$

$x = 0 ~~~ or ~~~ x = 1$

Since neither 0 nor 1 cause a zero in a denominator in the original equation, 0 and 1 are acceptable as solutions.

Answer: x = 0 or x = 1
