What is the sum written in scientific notation?

Answer:
Basically what you do is (the ^ arrow meaning exponent)

You take 3.7 + 4.45 x 10^20

Then 8.15 x 10^20, remove the decimal of 8.15 = 815 x 10^-2 x 10^20

815 x 10^18 = 815000000000000000000

You take 3.7 + 4.45 x 10^20

Then 8.15 x 10^20, remove the decimal of 8.15 = 815 x 10^-2 x 10^20

815 x 10^18 = 815000000000000000000

2.The expression 937(1+x) gives the markup price of a computer, where x is the percent of the markup written in decimal form.

Which part of the expression represents the percent, in decimal form, of the initial price that is being paid?

Enter your answer in the box.

**Answer:**

#1) 0.08x; #2) (1+x)

**Step-by-step explanation:**

#1) 0.08 is read as 8 hundredths. This can also be written as 8/100. Percent means out of 100; this means 8/100 is 8%. This means 0.08x is taking 8% of the original amount; this would represent the sales tax that is paid.

#2) In this problem, x is the percent of markup written in decimal form. This means that adding 1 to this number gives us 100% plus the percent of markup. This will give us the percentage of the original price that was paid, since we are paying 100% of the original price plus the markup.
