8.03 x 10^-8 + 32.8
To add these numbers together, you must use scientific notation.
We can rewrite 8.03 x 10^-8 as 0.0000000803 and keep the same number of significant figures.
Adding 0.0000000803 + 32.8, we get 32.8000000803.
Rounding to the correct number of significant figures, the sum is 32.8.
To add these two numbers, we need to first convert them to the same units. The first number, 8.03 x 10^-8, is written in scientific notation. This means that we can rewrite it as 0.0000000803. Now, we can add 0.0000000803 and 32.8.
0.0000000803 + 32.8 = 32.8000000803
Since the answer has a lot of decimal places, we can round it to a simpler form:
32.8000000803 ≈ 32.8
So, the sum of 8.03 x 10^-8 and 32.8 is approximately 32.8.
To add the numbers 8.03 x 10^-8 and 32.8, you need to convert them to the same exponent format. Let's first convert 32.8 to scientific notation:
32.8 = 3.28 x 10^1
Now, we can add them:
8.03 x 10^-8 + 3.28 x 10^1
Since the exponents are now the same (both 10^-8), we can add the coefficients:
8.03 x 10^-8 + 3.28 x 10^1 = (8.03 + 3.28) x 10^-8
Calculating the sum of the coefficients gives us:
11.31 x 10^-8
Finally, we can write the result as a number in scientific notation:
11.31 x 10^-8
