Answer:
Proved (See Explanation)
Step-by-step explanation:
Show that 3ⁿ⁺⁴ - 3ⁿ is divisible by 16.
This is done as follows
From laws of indices;
aᵐ⁺ⁿ = aᵐ * aⁿ.
So, 3ⁿ⁺⁴ can be written as 3ⁿ * 3⁴.
becomes
Factorize
3ⁿ * 5
5(3ⁿ)
<em>The expression can not be further simplified.</em>
<em>However, we can conclude that when 3ⁿ⁺⁴ - 3ⁿ is divisible by 16, because 5(3ⁿ) is a natural whole number as long as n is a natural whole number.</em>
Answer:
8.86 x 10^8
Step-by-step explanation:
Scientific notation means that you represent the standard form of a number like this:
number less than ten x 10 to the ___ power
In standard form, the decimal point is at the end of 886,000,000.
You have to move the decimal point to the left until it creates a number less than 10, but greater than 1:
8.86,000,000
You count how many decimal places you moved it. In this case, it is 8.
So your answer becomes 8.86 x 10^8
