Question

Subtract numbers in scientific notation practice
Calculate 6.25 x 10^6 - 4.73 x 10^6

Answer 1

To subtract the numbers in scientific notation, we first note that both numbers are expressed in terms of \( 10^6 \).

The calculation can be done as follows:

1. Write the numbers:
\[
6.25 \times 10^6 - 4.73 \times 10^6
\]

2. Since the terms are like terms (both are multiplied by \( 10^6 \)), we can simply subtract the coefficients:
\[
(6.25 - 4.73) \times 10^6
\]

3. Perform the subtraction of the coefficients:
\[
6.25 - 4.73 = 1.52
\]

4. Therefore, we rewrite the result:
\[
1.52 \times 10^6
\]

So, the answer is:
\[
1.52 \times 10^6
\]
