Calculate 6.25×106−4.73×106 . Express your answer in scientific notation to 2 decima

Answer 1

To subtract the two numbers in scientific notation, we need to have the same exponent.

$6.25 × 10^6 - 4.73 × 10^6$

First, we can subtract the numbers without the exponents:

$6.25 - 4.73 = 1.52$

Next, we can keep the original exponent and express our answer as $\boxed{1.52 × 10^6}$.
