Find 0.078−(5.2×10−3) . Express your answer in scientific notation. Do not round your answer.

9 answers

First, calculate the subtraction: 0.078 - (5.2 x 10^(-3)) = 0.078 - 0.0052.

Next, subtract the numbers to get 0.0728.

Expressing 0.0728 in scientific notation gives 7.28 x 10^(-2).
thats correct thanks
You're welcome! If you have any more questions, feel free to ask.
Earth’s radius is approximately 3,959 miles, while Jupiter’s radius is approximately 4.3441×104 miles. How much bigger is Jupiter’s radius compared to Earth’s? Express your answer in scientific notation. Do not round your answer.
To find how much bigger Jupiter's radius is compared to Earth's, we need to calculate the ratio of Jupiter's radius to Earth's radius.

Jupiter's radius = 4.3441 × 10^4 miles
Earth's radius = 3,959 miles

To calculate the ratio, we divide Jupiter's radius by Earth's radius:

Ratio = (4.3441 × 10^4) / 3,959

To divide these numbers, we need to convert Earth's radius to scientific notation:

Earth's radius = 3,959 = 3.959 × 10^3

Now we can perform the division:

Ratio = (4.3441 × 10^4) / (3.959 × 10^3)

To divide the numbers, we need to subtract the exponents:

Ratio = 4.3441 × 10^4 / 3.959 × 10^3 = (4.3441 / 3.959) × (10^4 / 10^3) = 1.0972 × 10^1

Therefore, Jupiter's radius is approximately 1.0972 × 10^1 times bigger than Earth's radius.
thats incorrect
Apologies for the mistake. Let's calculate again.

Jupiter's radius = 4.3441 × 10^4 miles
Earth's radius = 3,959 miles

To find how much bigger Jupiter's radius is compared to Earth's, we need to divide Jupiter's radius by Earth's radius:

Ratio = (4.3441 × 10^4) / 3,959

To make the division easier, let's convert Earth's radius to scientific notation:

Earth's radius = 3,959 = 3.959 × 10^3

Now we can perform the division:

Ratio = (4.3441 × 10^4) / (3.959 × 10^3)

To divide the numbers, we need to subtract the exponents:

Ratio = 4.3441 / 3.959 × 10^4 / 10^3 = 1.0967 × 10^1

Therefore, Jupiter's radius is approximately 1.0967 × 10^1 times bigger than Earth's radius.
the correct answer is 3.9482 * 10^4
you are incorrect
Apologies for the confusion. Let's recalculate the ratio correctly.

Jupiter's radius = 4.3441 × 10^4 miles
Earth's radius = 3,959 miles

To find how much bigger Jupiter's radius is compared to Earth's, we need to divide Jupiter's radius by Earth's radius:

Ratio = (4.3441 × 10^4) / 3,959

Now let's divide the numbers:

Ratio = 4.3441 × 10^4 / 3,959 = 1.0972 × 10^1

Therefore, Jupiter's radius is approximately 1.0972 × 10^1 times bigger than Earth's radius.

I apologize for the previous incorrect response. Thank you for pointing out the error.
