Calculate 6.25 x 10^6 - 4.73 x 10^6 express your answers in scientific notation to 2 decimal places
The calculation would be:
6.25 x 10^6 - 4.73 x 10^6 = (6.25 - 4.73) x 10^6 = 1.52 x 10^6
Therefore, the answer in scientific notation to 2 decimal places would be 1.52 x 10^6.
To calculate 6.25 x 10^6 - 4.73 x 10^6, we subtract the numbers in front of the powers of 10 and keep the same power of 10.
6.25 x 10^6 - 4.73 x 10^6 = (6.25 - 4.73) x 10^6
Simplifying the numbers in front of the powers of 10:
= 1.52 x 10^6
Expressing the answer in scientific notation to 2 decimal places, we have:
= 1.52 x 10^6
To calculate the subtraction of numbers in scientific notation, we need to ensure that the exponents are the same. In this case, both numbers have an exponent of 10^6.
First, let's subtract the base numbers: 6.25 - 4.73 = 1.52.
Now, let's subtract the exponents: 10^6 - 10^6 = 0.
Therefore, the result is 1.52 x 10^0.
In scientific notation, any number multiplied by 10^0 remains the same. So the final answer, expressed in scientific notation to 2 decimal places, is 1.52 x 10^0.
