Divide and write the result using scientific notation
the 8 and -4 is to the second power
8x10(8)
4x10(-4)
I plugged it in the calculator this way
(8x10^8)/(4x10^-4)
it gave me this as the result
2 E 12
2E12 means 2*10^12 , so your calculation is correct
how would I have known E equals 10. how you get that?
I have been using scientific notation for like 20 years, so I don't remember how I get that, sorry...
To divide numbers written in scientific notation, you can follow these steps:
Step 1: Divide the coefficients (the numbers before the "x") as you would in normal division.
8 ÷ 4 = 2
Step 2: Divide the powers of 10 by subtracting the exponent of the denominator from the exponent of the numerator.
8 - (-4) = 12
Step 3: Determine the sign of the result.
Since the exponent of 10 in the denominator is negative, the result will have a positive exponent of 10.
Putting it all together:
2 x 10^12
Therefore, the result of dividing (8x10^8) by (4x10^-4) is 2 x 10^12.
