Which logarithmic equation is equivalent to the exponential equation below?

aleksandr82 [10.1K]

Option B: $\ln 6=5 x$ is the correct answer.

Explanation:

The exponential equation is $e^{5 x}=6$

If $f(x)=g(x)$ , then $\ln (f(x))=\ln (g(x))$

Thus, the equation becomes

$\ln \left(e^{5 x}\right)=\ln (6)$

Applying log rule, $\log _{a}\left(x^{b}\right)=b \cdot \log _{a}(x)$ and thus the equation becomes

$5 x \ln (e)=\ln (6)$

Since, we know that, $\ln (e)=1$ , using this we get,

$5 x=\ln (6)$

Hence, the logarithmic equation which is equivalent to the exponential equation $e^{5 x}=6$ is $\ln 6=5 x$

Thus, Option B is the correct answer.

Choose the correct simplification of the expression (7x − 3)(4x^2 − 3x − 6).

-BARSIC- [3]

Distribute
(7x)(4x^2-3x-6)+(-3)(4x^2-3x-6)=
28x^3-21x^2-42x-12x^2+9x+18=
28x^3-21x^2-12x^2-42x+9x+18=
28x^3-33x^2-33x+18

D is the correct answer
