4.82×10^12 - 2.56×10^(-2)

Question

Show work in scientific notation.

Answer 1

To subtract two numbers in scientific notation, we need to make sure that the exponents are the same.

First, let's convert 2.56×10^(-2) to scientific notation with the same exponent as 4.82×10^12:

2.56×10^(-2) = 0.0256×10^12

Now we can subtract the numbers:

4.82×10^12 - 0.0256×10^12

Since the exponents are the same, we can subtract the coefficients:

4.82 - 0.0256 = 4.7944

The final answer in scientific notation is:

4.7944×10^12
