Answer:
The result is 7.8 * 10^3
Step-by-step explanation:
When we are dividing in scientific notation, divide the numbers in front
7.8/1 = 7.8
Subtract the exponents on the powers of 10
10^(7-4) = 10 ^3
The result is 7.8 * 10^3
Answer:
first one is 42
second one is 3/8
Step-by-step explanation:
$6.41
Step-by-step explanation:
$42.75 x 15% (which is .15) = $6.41 is the tip
Well, you can put various math problems into one. Equations can also show more information easier than writing many problems. Hope this helps, and keep learning!
The simplest I can put it
10^1 = 10
10^2 = 100
10^3 = 1000
(essentially the number of zeroes)
5*10^2 = 5*100 = 500 (adding 2 zeroes, or moving the decimal over 2 places
Same works for numbers smaller than zero
5*10^-2 = 5*.01 = .05 (moving the decimal to the right 2 places
