Answer 1

[AI-generated answer — Bot GPT 3.5]

To calculate the difference between 8.03 × 10^-8 and 2.56 × 10^-2, we subtract them as follows:

8.03 × 10^-8 - 2.56 × 10^-2 = (8.03 - 2.56) × 10^-8

Performing the subtraction gives us:

5.47 × 10^-8

Answer 2

8.03 ✕ 10^-8 - 2.56 ✕ 10^-2

Answer 3

To subtract 8.03 × 10^-8 from 2.56 × 10^-2, we can simply subtract the coefficients and keep the same exponent:

= (2.56 - 8.03) × 10^-2

= (-5.47) × 10^-2

Therefore, the result is -5.47 × 10^-2.

Answer 4

[AI-generated answer — Step-by-Step Bot]

To subtract the numbers 8.03 ✕ 10^-8 and 2.56 ✕ 10^-2, follow these steps:

Step 1: Check the exponents.
The exponents of both numbers are negative. Since we need to subtract the numbers, we will keep the exponent with the larger absolute value, which is -2.

Step 2: Adjust the decimal places.
To align the decimal places, we need to move the decimal point 6 places to the right in the first number, as the exponent is -8. The second number is already in the correct position.

8.03 ✕ 10^-8 becomes 0.00000803.
2.56 ✕ 10^-2 remains the same.

Step 3: Perform the subtraction.
Now subtract 0.00000803 from 2.56 ✕ 10^-2:

2.56 ✕ 10^-2 - 0.00000803 =
0.0256 - 0.00000803 =
0.02559197

So, the result of subtracting 8.03 ✕ 10^-8 from 2.56 ✕ 10^-2 is 0.02559197.

To subtract 8.03 ✕ 10^-8 from 2.56 ✕ 10^-2 step by step, follow these steps:

Step 1: Adjust the exponents.
The exponents are different, so we need to adjust them to have the same exponent. In this case, we can convert 8.03 ✕ 10^-8 to scientific notation with the same exponent as 2.56 ✕ 10^-2.

8.03 ✕ 10^-8 = 0.0000000803 ✕ 10^-2

Step 2: Perform the subtraction.
Now subtract 0.0000000803 ✕ 10^-2 from 2.56 ✕ 10^-2:

2.56 ✕ 10^-2 - 0.0000000803 ✕ 10^-2 =
(2.56 - 0.0000000803) ✕ 10^-2 =
2.5599999197 ✕ 10^-2

Final Answer:
So, the result of subtracting 8.03 ✕ 10^-8 from 2.56 ✕ 10^-2 is approximately 2.5599999197 ✕ 10^-2.

Answer 7

[AI-generated answer — Explain Bot]

To subtract these two numbers written in scientific notation (also known as standard form), you need to make sure that the exponents are the same.

Let's rewrite the numbers with the same exponent:

8.03 × 10^-8 can be written as 0.803 × 10^-7 (by moving the decimal point one place to the right).

Now we can subtract the two numbers:

0.803 × 10^-7 - 2.56 × 10^-2

When subtracting, we only need to focus on the significands or the numbers that are not multiplied by 10 raised to a power.

In this case, we subtract 0.803 from 2.56:

2.56 - 0.803 = 1.757

Now we need to keep the same exponent 10^-7:

1.757 × 10^-7

So, 8.03 × 10^-8 - 2.56 × 10^-2 = 1.757 × 10^-7.
