Problem

Solve for d square root of (50x^6y^3)/(9x^8)=(5y^6 square root of 2y)/(dx)

The problem provided is a mathematical equation that involves solving for the variable 'd'. The equation includes a radical expression on both sides, specifically the square root of a rational expression involving powers of x and y on the left, and a product of a monomial, the square root of a variable, and another variable on the right. The task is to manipulate the equation to isolate 'd' and express it in terms of the other variables and constants present in the equation. This would likely require knowledge of algebraic operations involving roots and rational expressions, as well as the properties of exponents.

Solution:

Step 1

Express the given equation in a simplified form: $\frac{5y^6\sqrt{2y}}{dx} = \sqrt{\frac{50x^6y^3}{9x^8}}$.

Step 2

Simplify both sides of the equation.

Step 2.1

Reduce the fraction $\frac{50x^6y^3}{9x^8}$ by eliminating common factors.

Step 2.1.1

Extract $x^6$ from the numerator: $\frac{5y^6\sqrt{2y}}{dx} = \sqrt{\frac{x^6(50y^3)}{9x^8}}$.

Step 2.1.2

Extract $x^6$ from the denominator: $\frac{5y^6\sqrt{2y}}{dx} = \sqrt{\frac{x^6(50y^3)}{x^6(9x^2)}}$.

Step 2.1.3

Cancel out $x^6$: $\frac{5y^6\sqrt{2y}}{dx} = \sqrt{\frac{50y^3}{9x^2}}$.

Step 2.1.4

Rewrite the simplified expression: $\frac{5y^6\sqrt{2y}}{dx} = \sqrt{\frac{50y^3}{9x^2}}$.

Step 2.2

Express $\frac{50y^3}{9x^2}$ as $\left(\frac{5y}{3x}\right)^2(2y)$.

Step 2.2.1

Factor out $(5y)^2$ from $50y^3$: $\frac{5y^6\sqrt{2y}}{dx} = \sqrt{\frac{(5y)^2 \cdot 2y}{9x^2}}$.

Step 2.2.2

Factor out $(3x)^2$ from $9x^2$: $\frac{5y^6\sqrt{2y}}{dx} = \sqrt{\frac{(5y)^2 \cdot 2y}{(3x)^2}}$.

Step 2.2.3

Reorganize the fraction: $\frac{5y^6\sqrt{2y}}{dx} = \sqrt{\left(\frac{5y}{3x}\right)^2(2y)}$.

Step 2.3

Extract terms from under the radical: $\frac{5y^6\sqrt{2y}}{dx} = \frac{5y}{3x}\sqrt{2y}$.

Step 2.4

Combine $\frac{5y}{3x}$ and $\sqrt{2y}$: $\frac{5y^6\sqrt{2y}}{dx} = \frac{5y\sqrt{2y}}{3x}$.

Step 3

Cross-multiply the numerators and denominators: $5y^6\sqrt{2y}(3x) = dx(5y\sqrt{2y})$.

Step 4

Isolate $d$ to solve the equation.

Step 4.1

Rearrange the equation: $dx(5y\sqrt{2y}) = 5y^6\sqrt{2y}(3x)$.

Step 4.2

Simplify the equation.

Step 4.2.1

Remove parentheses: $dx(5y\sqrt{2y}) = 5y^6\sqrt{2y}(3x)$.

Step 4.2.2

Multiply $3$ by $5$: $dx(5y\sqrt{2y}) = 15y^6\sqrt{2y}x$.

Step 4.3

Divide both sides by $x(5y\sqrt{2y})$ and simplify.

Step 4.3.1

Divide the equation: $\frac{dx(5y\sqrt{2y})}{x(5y\sqrt{2y})} = \frac{15y^6\sqrt{2y}x}{x(5y\sqrt{2y})}$.

Step 4.3.2

Simplify the left side by canceling common factors: $d = \frac{15y^6\sqrt{2y}x}{x(5y\sqrt{2y})}$.

Step 4.3.3

Simplify the right side by canceling common factors: $d = \frac{3y^5x}{x}$.

Step 4.3.4

Cancel the common factor of $x$: $d = 3y^5$.
