How many times larger is 8*10^6 than 2*10^2
bogdanovich [222]
The first step for solving this question is put both of your given expressions into one and then subtract them. This will look like the following:
8 × 10^{6} - 2 × 10²]
Now to make the calculation easier,, factor the expression.
(8 × 10^{4} - 2) × 10²
Evaluate the power inside the parenthesis.
(8 × 10000 - 2) × 10²
Evaluate the power outside the parenthesis.
(8 × 10000 - 2) × 100
Multiply the numbers inside the parenthesis.
(80000 - 2) × 100
Subtract the numbers in the parenthesis.
79998 × 100
Lastly,, multiply the numbers together to get your final answer.
7999800
This means that 8 × 10^{6} is 7999800 times larger than 2 × 10².
Let me know if you have any further questions.

At the movie theatre, child admission is
Dmitriy789 [7]
Child = $5.70
Adult = $9.80

- We can conclude that the amount of adult is double the amount of child tickets bought. (total of $556.60)

For this, you will need to divide the total amount by two and draw a tree chart with each of the numbers to get the seperation of the two. I would find out how many 9.80s or 5.70s go into $56.60 so you'll just have $500
