Math Problem Statement

Solve for x and y.{logš‘„+logš‘¦2=3logš‘„3+logš‘¦3=6

Solution

To solve for xx and yy given the system of logarithmic equations:

\log x + \log y^2 = 3 \\ \log x^3 + \log y^3 = 6 \end{cases}$$ we can follow these steps: 1. Use logarithm properties to simplify the equations: - $$\log x + \log y^2$$ can be rewritten as $$\log(x) + 2\log(y)$$ - $$\log x^3 + \log y^3$$ can be rewritten as $$3\log(x) + 3\log(y)$$ So the system becomes: $$\begin{cases} \log(x) + 2\log(y) = 3 \\ 3\log(x) + 3\log(y) = 6 \end{cases}$$ 2. Simplify the second equation by dividing all terms by 3: $$\log(x) + \log(y) = 2$$ 3. Now we have the system: $$\begin{cases} \log(x) + 2\log(y) = 3 \\ \log(x) + \log(y) = 2 \end{cases}$$ 4. Subtract the second equation from the first equation to eliminate $$\log(x)$$: $$(\log(x) + 2\log(y)) - (\log(x) + \log(y)) = 3 - 2$$ $$\log(y) = 1$$ 5. Solve for $$y$$: $$y = 10^1 = 10$$ 6. Substitute $$\log(y) = 1$$ back into the second equation: $$\log(x) + 1 = 2$$ $$\log(x) = 1$$ 7. Solve for $$x$$: $$x = 10^1 = 10$$ Thus, the solutions to the system are: $$x = 10 \quad \text{and} \quad y = 10$$ Do you want details or have any questions?
