Engineering notation of the number (8.2 × 103) × (5.0 × 104) is
4.39192 × 10⁵
OR
4.4 ₓ 10⁵.
<h3>What is engineering notation ?</h3>
Engineering notation is same as scientific notation.
According to the given question
Converting (8.2 × 103) × (5.0 × 104) to engineering notation can be done using a base and raising it to the power of 10.
Base can be greater than or equal to 1 and less than 10.
Suppose base is a
∴ 1≤a<10 and the number in engineering notation will be of the form a×10ⁿ
Given (8.2 × 103) × (5.0 × 104) which is
= 844.6 × 520
= 439192
=4.39192 × 10⁵
= 4.4 ₓ 10⁵.

Hi there! We are given the expression:

To condense or simplify the following logarithm. You have to remember these properties:
Properties - Logarithm

These two properties are what we need for our problem. Therefore,

We use the log_b(a)^n = nlog_b(a) property to convert in the form above. Next, we use the second property.

Answer
- log base 4 of (a^5/b^6) is our simplifed form.
Any questions can be asked through comment as I may reply soon. Thanks for using Brainly! Have a good day and happy learning! :)

Answer: 6.93 years
Step-by-step explanation:
Given
Rate of interest is 
Future value is given by 
For the investment to double itself, i.e. 

It takes around 6.93 years to double the investment.
You know b=0 because it is passing through the orgin (0,0) and b is the y intercept. You input (-3,6) as (x,y)
