Which of the following is true regarding the solution to the logarithmic equation below? log Subscript 2 Baseline (x + 11) = 4.

meriva

Answer:

Option C.

Step-by-step explanation:

The given logarithmic equation is

$\log_2(x+11)=4$

It can be written as

$(x+11)=2^4$ $[\because log_ax=y\Leftrightarrow x=a^y]$

$x+11=16$

$x=5$

Now, to check whether $x=5$ is a true solution or not. Substitute $x=5$ in the LHS of given equation.

$LHS=\log_2(5+11)$

$LHS=\log_2(16)$

$LHS=\log_22^4$

$LHS=4$ $[\because log_aa^x=x]$

$LHS=RHS$

Hence, $x=5$ is a true solution because $\log_2(16)=4$ .

Therefore, the correct option is C.

P − 10p + -5p + 14p − -9p − 2 = -20

djverab [1.8K]

You will need to work left to right.

p - 10p + -5p +14p - -9p - 2 = -20

-9p + -5p +14p - -9p - 2 = -20

-14p +14p - -9p - 2 = -20

0p- -9p - 2 = -20

9p - 2 = -20

Then you will want to eliminate 2 by adding it to both sides

9p = -18

Then divide by 9 to isolate P

p=-2

Simplify 2√2-√3<br> ---------------<br> √2+√3

serious [3.7K]

Step-by-step explanation:

$= \frac{2 \sqrt{2} - \sqrt{3} }{ \sqrt{2} + \sqrt{3} }$

$= \frac{2 \sqrt{2} - \sqrt{3} }{ \sqrt{2} + \sqrt{3} } \times \frac{ \sqrt{2} - \sqrt{3} }{ \sqrt{2} - \sqrt{3} }$

$= \frac{ 2( \sqrt{2} - \sqrt{3} )( \sqrt{2} - \sqrt{3} )}{ { \sqrt{2} }^{2} - { \sqrt{3} }^{2} }$

$= \frac{2(2 - \sqrt{6} - \sqrt{6} - 3) }{2 - 3}$

$= \frac{2( - 1 - 2 \sqrt{6} )}{ - 1}$

$= \frac{ - 2(1 + 2 \sqrt{6} )}{ - 1}$

$= 2(1 + 2 \sqrt{6} )$

$= 2 + 4 \sqrt{6}$
