Click For Summary
To solve the logarithmic equation 7(3+7x) = 3(4-2x), take the logarithm of both sides. This transforms the equation into a linear form in terms of x. After applying logarithmic properties, standard methods can be used to solve for x. The approach simplifies the problem and allows for straightforward calculations. This method effectively resolves the logarithmic equation.

Hi there datafiend,

Take the logarithm on both sides of the equation $7^{(3 + 7x)} = 3^{(4 - 2x)}$. This will give you a linear equation in $x$, which you can solve by usual methods.

Thread 'Erroneously finding discrepancy in transpose rule'

Obviously, there is something elementary I am missing here. To form the transpose of a matrix, one exchanges rows and columns, so the transpose of a scalar, considered as (or isomorphic to) a one-entry matrix, should stay the same, including if the scalar is a complex number. On the other hand, in the isomorphism between the complex plane and the real plane, a complex number a+bi corresponds to a matrix in the real plane; taking the transpose we get which then corresponds to a-bi...
