Calculate 6.25 x 10^6 -4.73 x 10^6. Express the answer in scientific Notation to 2 decimal places.
To calculate 6.25 x 10^6 - 4.73 x 10^6, we need to subtract the numbers and keep the same exponent of 10 since the numbers are in scientific notation.
Step 1: Subtract the coefficients: 6.25 - 4.73 = 1.52.
Step 2: Keep the exponent of 10 the same. In this case, the exponent is 6.
Therefore, the answer is 1.52 x 10^6.
Expressed in scientific notation with two decimal places, the answer is 1.52 x 10^6.
To subtract these numbers, we must have the same exponent for 10. Therefore, we can rewrite 6.25 x 10^6 as 625 x 10^4 and 4.73 x 10^6 as 473 x 10^4.
Subtracting these numbers, we get:
625 x 10^4 - 473 x 10^4 = (625 - 473) x 10^4 = 152 x 10^4
To express this answer in scientific notation, we can rewrite 152 as 1.52 x 10^2. Thus, the final answer is:
1.52 x 10^2 x 10^4 = 1.52 x 10^(2+4) = 1.52 x 10^6
To calculate the subtraction of numbers in scientific notation, you need to ensure that the exponents of the numbers are equal. If they are not equal, you need to adjust them before performing the subtraction.
Let's calculate the subtraction step by step:
Step 1: Adjust the exponents
In this case, the exponents 6 and 6 are already equal, so no adjustment is needed.
Step 2: Perform the subtraction
Subtract the values of the coefficients (the numbers multiplied by 10 raised to the exponent).
6.25 x 10^6 - 4.73 x 10^6 = (6.25 - 4.73) x 10^6
Step 3: Calculate the answer
Perform the subtraction of the coefficients: 6.25 - 4.73 = 1.52
Now, express the answer in scientific notation with 2 decimal places:
1.52 x 10^6
Therefore, the answer is 1.52 x 10^6 in scientific notation with 2 decimal places.
