Separate the fraction into two parts: $\sqrt{\frac{0.000001}{4}\cdot \frac{(487x-35999{)}^2}{1}}$

Step 6: Divide the factors

Divide $0.000001$ by $4$: $\sqrt{0.00000025\cdot \frac{(487x-35999{)}^2}{1}}$

Step 7: Simplify by canceling common factors

Step 7.1: Factor out from the numerator

Factor $0.00000025$ from the numerator: $\sqrt{0.00000025\cdot \frac{(487x-35999{)}^2}{0.00000025\cdot 4000000}}$

Step 7.2: Cancel the common factors

Cancel out $0.00000025$: $\sqrt{\frac{(487x-35999{)}^2}{4000000}}$

Step 7.3: Rewrite the simplified expression

Rewrite the expression without the canceled factor: $\sqrt{\frac{(487x-35999{)}^2}{4000000}}$

Step 8: Express the denominator as a square

Rewrite $4000000$ as $(2000{)}^2$: $\sqrt{\frac{(487x-35999{)}^2}{(2000{)}^2}}$

Step 9: Rewrite as a single fraction under the radical

Combine the terms under the radical: $\sqrt{{\left(\frac{487x-35999}{2000}\right)}^2}$

Step 10: Simplify the square root

Simplify the radical assuming positive real numbers: $\frac{487x-35999}{2000}$

Knowledge Notes:

The problem involves simplifying a square root of a fraction where the numerator is a squared term and the denominator is a simple subtraction. The steps taken to simplify the expression involve factoring out common terms, applying the square of a product rule, simplifying the denominator, separating fractions, and canceling common factors.

Relevant knowledge points include:

• Factoring: The process of breaking down an expression into its constituent factors.

• Square of a product rule: $(ab{)}^2=a^2{b}^2$, which is used to simplify the square of a product of two terms.

• Simplifying fractions: The process of reducing the numerator and denominator to their simplest form by canceling common factors.

• Square roots: The operation of finding a number which, when multiplied by itself, gives the original number. When a square root is applied to a squared expression, it simplifies to the base of the square, provided that the base represents a positive real number.

In this problem, the square root and the squared term cancel each other out, leaving a simplified fraction. The final result is obtained by recognizing that the square root of a square cancels out, assuming we are dealing with positive real numbers.
