How do you divide and multiply in scientific notation?
Suppose p = a*10^x and
q = b*10^y are two numbers in scientific notation.
Then p*q = (a*b)*10^(x+y)
where, 1 <= |a|,|b| < 10 implies that 1 <= |a*b| < 100.
If a*b is greater than or equal to 10, let a*b = 10*c
then in scientific notation, p*q = c*10^(x+y+1).
Also p/q = (a/b)*10^(x-y)
where, 1 <= |a|,|b| < 10 implies that 0 < |a/b| <= 1.
If a/b is less than 1, let a/b = c/10
then in scientific notation, p/q = c*10^(x-y-1).
How do you convert -38600000 to scientific notation?
-38,600,000.
take the decimal place and move it to the left until you have only one number left of the decimal place... like this
-3.86
now count out how many times you move over the decimal place... you move it 7 times. multiply your number of -3.86 by 107
-3.86*107
