Answer:

Step-by-step explanation:
Given

Required
Rewrite using scientific notation, then find n

Express as fraction

This can be splitted to

The first number must be between 1 and 10; hence, 25 can be expressed as 2..5 * 10

Apply law of indices


Comparing n, the given options

Answer:
9abc(ac² - 3)
Step-by-step explanation:
<u>Given polynomial:</u>
<u>Factors of the terms:</u>
- 9a²bc³ = 3*3*a*a*b*c*c*c
- 27abc = 3*3*3*a*b*c
<u>Common factors of the above: </u>
<u>So the answer:</u>
- 9a²bc³ -27abc = 9abc(ac² - 3)
We know that we can use trigonometry to solve for x here.
If we use tangent, we can solve for x directly:




So therefore we have solve for x, which is D)
