Determine the sum: 21.6 x 10^4 + 5.2 x 10^7. Write your answer in scientific notation.

Step by step for 7,9, 11. EVEN IF U CANT DO ALL, u can help with 1 or 2. Ill mark brainly.

Answer:

7) $4 \ log_3(x) - 4 \ log_3(y)$

9) $5log_4(7) - 5log_4(12)$

11) $5log_5 \ (x) - log_5 \ (y)$

Step-by-step explanation:

$log_3 (\frac{x}{y})^{4}$

----------------------------------------------------------------------------------------------------

Use Logarithm of a Quotient which states

$log_b \frac{M}{N} = log_b M-log_bN$

And also use Logarithm of a Power which states

$log_b\ M^{n} = n\log_bM$

----------------------------------------------------------------------------------------------------

So using these two properties,

7. $4 \ log_3(x) - 4 \ log_3(y)$

----------------------------------------------------------------------------------------------------

For #9, use the same logarithm propertied

$log_4(\frac{7}{12})^5 = 5log_4(7) - 5log_4(12)$

----------------------------------------------------------------------------------------------------

#11 is also the same concept

$log_5\ \frac{x^5}{y} = 5log_5 \ (x) - log_5 \ (y)$

It is not - 5 log5(y) since only x is to the power of 5 not y

----------------------------------------------------------------------------------------------------

Hope this is what you were looking for and helps you! Have a nice day/night :)

The measure of angle m is 57 degrees. what is the measure of its complementary angle?

KatRina [158]

Complementary angles add up to 90*, so the measurement would be equal to 33*.

Solve x/12+3<7<br> thanks!

Bezzdna [24]

Answer:

x < 48

Step-by-step explanation:

First, subtract 3 from both sides of this inequality: x/12 < 4.

Multiply both sides of this inequality by 12 to remove fractions: x < 48
