What is the relationship between exponentials and logarithms? How can you use these to solve equations? Provide an example in yo

Sveta_85 [38]

Answer:

Exponentials and logarithms are inverses of each other.

Step-by-step explanation:

Exponentials and logarithms are inverses of each other.

For logarithmic function:

Domain = $\left ( 0,\infty \right )$ , Range = $\left ( -\infty ,\infty \right )$

Vertical asymptote is y - axis.

x - intercept is (1,0)

For exponential function:

Domain = $\left ( -\infty ,\infty \right )$ , Range = $\left ( 0,\infty \right )$

Horizontal asymptote is x - axis.

y- intercept is (0,1)

Both exponential and logarithmic functions are increasing.

For example:

Solve: $\log x=\frac{\log 5+\log 3}{\log 3^2}$

$\log x=\frac{\log 5+\log 3}{\log 3^2}\\\log x=\frac{\log (5\times 3)}{2\log 3}\,\,\left \{ \because \log (ab)=\log a+\log b\,,\,\log a^b=b\log a \right \}\\=\frac{\log 15}{2\log 3}$

$\Rightarrow \log x=\frac{\log 15}{2\log 3}\\\Rightarrow x=e^{\frac{\log 15}{2\log 3}}\,\,\left \{ \because \log x=y\Rightarrow x=e^y \right \}$

PLZ HELP 6th grade math, problems attached

GREYUIT [131]

Given expression: $4 x^{2}+2 y$ for x = 3 and y = –2

(6) Mistake did by Grayson:

In second step, first to do 3² and then multiply with 4.

But Grayson first multiply 4 with 3 and then squared the expression.

This is wrong.

(7) Mistake did by Emily:

In third step, first to multiply 2 with (–2) using BODMAS rule and then add with 36.

But Emily first added 36 with 2 which gives 38.

This is wrong.

(8) Mistake did by Pat:

In first step, the y value given is –2.

But Pat substituted y value is 2.

This is wrong.

(9) Correct evaluation:

$4 x^{2}+2 y=4(3)^{2}+2(-2)$

$=36+2(-2)$

$=36+(-4)$

$=32$

This is the correct way to evaluate the given expression.
