] | Those numbers aren't really exceptions to the magic number rule.

For example:
```
int Rows = 2;
int Cols = 2;
```
Is a pretty valid example where usage of raw values will be misleading.

2,633,797 | $$\text{Solve for $x$}\begin{cases} (x+1)^{\log\_{10}(x+1)} &= 100(x+1) \\ 3^{(\log\_3x)^2}+x^{\log\_3x}&=162\end{cases}$$
Can we take $\log$ both sides but it did not work for me. I am not getting. What other properties can we apply here?

] | $(x+1)^{log\_{10}x+1 } = 100(x+1)$. Take log of both sides:
$\log\_{10} (x+1)^{\log\_{10}(x+1)} = \log\_10 100(x+1)$
$\log\_{10}(x+1)\*\log\_{10}(x+1) = \log\_{10} 100 + \log\_{10}(x+1)$.
$\log\_{10}^2(x+1) = 2 + \log\_{10}(x+1)$
$\log\_{10}^2(x+1)-\log\_{10}(x+1)-2 = 0$
....
$3^{(\log\_3x)^2}+x^{\log\_3x}=162$
... | $$x^{\log\_3x}=\left(3^{\log\_3x}\right)^{\log\_3x}=3^{\log\_3^2x}.$$
Thus, the second equation gives $$2\cdot3^{\log\_3^2x}=162$$ or
$$3^{\log\_3^2x}=3^4$$ or
$$\log\_3^2x=4,$$ which gives $x=9$ or $x=\frac{1}{9}.$ |
