Calculate 6.25x10^6-4.73x10^6. Express your answer in scientific notation to 2 decimal places.
6.25x10^6 - 4.73x10^6 can be written as (6.25 - 4.73)x10^6 = 1.52x10^6.
Rounded to 2 decimal places, the expression 1.52x10^6 in scientific notation is 1.52x10^6. Answer: \boxed{1.52 \times 10^6}.
To calculate the subtraction of these two numbers in scientific notation, you need to subtract the coefficients and keep the same exponent.
Step 1: Subtract the coefficients: 6.25 - 4.73 = 1.52
Step 2: Keep the exponent of 10^6.
Therefore, 6.25x10^6 - 4.73x10^6 = 1.52x10^6
Expressing the answer in scientific notation to 2 decimal places, it becomes 1.52x10^6.
To calculate the subtraction of numbers in scientific notation, we need to make sure that the powers of 10 are the same.
In this case, we have:
6.25 x 10^6 - 4.73 x 10^6
To ensure that the powers of 10 are the same, we can rewrite 4.73 x 10^6 as 0.473 x 10^7.
Now, we can subtract the two numbers:
6.25 x 10^6 - 0.473 x 10^7
To subtract these numbers, we only need to subtract their coefficients:
6.25 - 0.473 = 5.777
As for the power of 10, it remains the same:
10^6
So, the result is 5.777 x 10^6.
To express the answer in scientific notation to 2 decimal places, we round the coefficient to the nearest hundredth:
5.78
Therefore, the final answer in scientific notation to 2 decimal places is:
5.78 x 10^6.
