3.2 × 10^4 + 1.95 × 10^6. scientific notation subtracting

9 answers

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:

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.

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
