b. Subtract 1.95 x 106 and 3.2 x 104
To subtract 1.95 x 10^6 from 3.2 x 10^4, we can align the numbers by their exponents:
3.2 x 10^4
- 1.95 x 10^6
To subtract, we subtract the coefficients and keep the exponent the same:
3.2 - 1.95 = 1.25
So the coefficient is 1.25. Since 3.2 x 10^4 has a smaller exponent than 1.95 x 10^6, we keep the exponent as 10^4 for our answer.
Therefore, the result of the subtraction is 1.25 x 10^4 in scientific notation.
To subtract 1.95 x 10^6 and 3.2 x 10^4 in correct scientific notation, follow these steps:
Step 1: Align the numbers by writing them in the same power of 10.
- 1.95 x 10^6 and 3.2 x 10^4
Step 2: Subtract the numbers individually while keeping the power of 10 unchanged.
- 1.95 x 10^6 - 3.2 x 10^4 = 1.95 x 10^6 - 0.032 x 10^6
Step 3: Simplify the subtraction by performing the arithmetic.
- 1.95 x 10^6 - 0.032 x 10^6 = (1.95 - 0.032) x 10^6
- 1.918 x 10^6
So the difference between 1.95 x 10^6 and 3.2 x 10^4 is 1.918 x 10^6 in correct scientific notation.
To subtract 1.95 x 10^6 and 3.2 x 10^4, follow these steps:
Step 1: Write down the given numbers in scientific notation:
1.95 x 10^6
3.2 x 10^4
Step 2: Align the exponents:
Make sure the exponents are aligned. In this case, we have 10^6 and 10^4.
Step 3: Perform the subtraction:
In scientific notation, you can only subtract numbers when the exponents are the same. To make the exponents match, decrease the exponent of 1.95 x 10^6 by 2, resulting in 1.95 x 10^4.
Now, subtract 1.95 x 10^4 from 3.2 x 10^4:
3.2 x 10^4
- 1.95 x 10^4
________________
= (3.2 - 1.95) x 10^4
Step 4: Calculate the difference:
Subtract the coefficients, 3.2 - 1.95, which equals 1.25.
1.25 x 10^4
Thus, the subtraction of 1.95 x 10^6 and 3.2 x 10^4 gives the result 1.25 x 10^4 in scientific notation.
