What is the exact solution for the equation

Nostrana [21]

Answer:

Option C is correct.

Exact solution of $2^{x+2} = 5^{2x}$ is, $\frac{2\ln 2}{2\ln 5 - \ln 2}$

Step-by-step explanation:

Given the equation: $2^{x+2} = 5^{2x}$

Using logarithmic rules:

$a^x=b^y$ ⇒ $x \ln a =y \ln b$

$\ln x^a = a\ln x$

Given: $2^{x+2} = 5^{2x}$

Taking logarithmic both sides:

$\ln 2^{x+2} = \ln 5^{2x}$

By logarithmic rules;

$(x+2) \ln 2 = (2x) \ln 5$

Using distributive property i.e $a\cdot (b+c) = a\cdot b + a\cdot c$

$x \ln 2 +2 \ln 2 = 2x \ln 5$

Subtract $x \ln 2$ from both sides we get;

$x \ln 2 +2 \ln 2 - x \ln 2= 2x \ln 5 - x \ln 2$

Simplify:

$2 \ln 2= 2x \ln 5 - x \ln 2$

or

$2 \ln 2= x (2\ln 5 - \ln 2)$

Divide both sides by $(2\ln 5 - \ln 2)$ we get;

$\frac{2\ln 2}{2\ln 5 - \ln 2} = x$

Therefore, the exact solution of the given equation is $\frac{2\ln 2}{2\ln 5 - \ln 2}$

What is the product? Assume x ≠ 0. 2x^2/3{6/x} 3x 4x 3x2 4x2

Serjik [45]

Answer:

4x

Step-by-step explanation:

The given product is;

$\frac{2x^2}{3}(\frac{6}{x})$

This is the same as;

$\frac{2x^2\times 6}{3\times x}$

We cancel out the common factors to obtain;

$\frac{2x\times 2}{1\times 1}$

Multiply out to obtain;

$\frac{4x}{1}$

Simplify

$4x$

The second option is the correct choice.
