3.2 × 10^4 + 1.95 × 10^6. scientific notation subtracting
To subtract numbers in scientific notation, the exponents must be equal. To achieve this, one of the numbers must be adjusted by moving the decimal point.
Let's subtract:
3.2 × 10^4 + 1.95 × 10^6
First, adjust the number 3.2 × 10^4 by moving the decimal point two places to the right, so it becomes 32 × 10^4.
Now the exponents are equal, and we can subtract the numbers:
(32 × 10^4) + (1.95 × 10^6) = 1.95 × 10^6 + 32 × 10^4
Next, subtract the coefficients:
1.95 + 32 = 33.95
Finally, the result is in scientific notation:
33.95 × 10^4
Therefore, the result of 3.2 × 10^4 + 1.95 × 10^6 in scientific notation is 33.95 × 10^4.
wrong
Apologies for the mistake. Let's try the correct calculation:
To subtract numbers in scientific notation, the exponents must be the same. Let's subtract:
3.2 × 10^4 + 1.95 × 10^6
To make the exponents the same, we need to adjust the first number.
The number 3.2 × 10^4 can be expressed as 0.032 × 10^6 (moving the decimal point two places to the left and changing the exponent accordingly).
Now we have:
0.032 × 10^6 + 1.95 × 10^6 = (0.032 + 1.95) × 10^6
Adding the coefficients, we get:
1.982 × 10^6
Therefore, the result of 3.2 × 10^4 + 1.95 × 10^6 in scientific notation is 1.982 × 10^6.
fix the 1.982
Apologies for the mistake. Let's correct the calculation:
To subtract numbers in scientific notation, the exponents must be the same. Let's subtract:
3.2 × 10^4 + 1.95 × 10^6.
To make the exponents the same, we need to adjust the first number.
The number 3.2 × 10^4 can be expressed as 0.00032 × 10^6 (moving the decimal point four places to the left and changing the exponent accordingly).
Now we have:
0.00032 × 10^6 + 1.95 × 10^6 = (0.00032 + 1.95) × 10^6.
Adding the coefficients, we get:
1.95032 × 10^6.
Therefore, the result of 3.2 × 10^4 + 1.95 × 10^6 in scientific notation is 1.95032 × 10^6.
its this -1.918 × 10^6
Apologies for the confusion. Let's correct the calculation:

3.2 × 10^4 + 1.95 × 10^6.
To make the exponents the same, we need to adjust the first number.
The number 3.2 × 10^4 can be expressed as 0.00032 × 10^6 (moving the decimal point four places to the left and changing the exponent accordingly).

1.95032 × 10^6.
However, we are subtracting these numbers, so we have:
1.95 × 10^6 - 0.00032 × 10^6 = (1.95 - 0.00032) × 10^6.
Subtracting the coefficients, we get:
1.94968 × 10^6.
Therefore, the result of 3.2 × 10^4 + 1.95 × 10^6 in scientific notation is 1.94968 × 10^6.
no thats wrong this is right -1.918 × 10^6

To subtract numbers in scientific notation, you need to make sure that the exponents are the same. Here's how you can subtract 3.2 × 10^4 from 1.95 × 10^6 in scientific notation:
Step 1: Adjust the exponents
Since 10^4 and 10^6 have a difference of 2 in their exponents, you need to adjust one of the numbers to have the same exponent as the other. In this case, let's adjust 3.2 × 10^4 to match the exponent of 10^6.
To adjust, we need to move the decimal point in 3.2 two places to the right. This gives us 320. Now, we can express it in scientific notation as 3.20 × 10^6.
Step 2: Subtract the adjusted numbers
Now that the exponents are the same, we can subtract the coefficients. 1.95 - 3.20 = -1.25.
Step 3: Keep the exponent
Since the exponents are the same, we can keep the common exponent of 10^6.
Therefore, the subtraction of 3.2 × 10^4 from 1.95 × 10^6 in scientific notation is -1.25 × 10^6.
