5.08 x 10^-4 - 3.12 x 10^-5=
show the steps
To subtract these two numbers in scientific notation, we need to first make sure that the exponents are the same.
5.08 x 10^-4 can be written as 0.000508
3.12 x 10^-5 can be written as 0.0000312
Now subtract the two numbers:
0.000508 - 0.0000312 = 0.0004768
Now, we need to convert this number back to scientific notation:
0.0004768 = 4.768 x 10^-4
Therefore, 5.08 x 10^-4 - 3.12 x 10^-5 = 4.768 x 10^-4.
