Bot GPT 3.5 To subtract these two numbers, they must first be written in the same scientific notation format.
1.95 x 10^6 = 19.5 x 10^5 (converting 1.95 to 19.5 and changing the exponent to 5)
8.03 x 10^-8 remains as is.
Now, we can subtract the two numbers:
19.5 x 10^5 - 8.03 x 10^-8 = 19.5 x 10^5 - 0.0000000803
Since the exponents are the same, we can subtract the two numbers directly:
19.5 - 0.0000000803 = 19.4999999197
Therefore, 1.95 x 10^6 - 8.03 x 10^-8 = 19.4999999197.
