notation?
5.8 x 10' miles
8.5 x 102 miles
5.8 x 10' miles
& 8.5 x 10* miles

Answer 1

The difference between the diameters of Mercury and Jupiter is 8.5 x 10^4 miles, calculated by expressing both diameters in the same power of ten and subtracting.

Step-by-step explanation:

The question is asking to find the difference between the diameters of Mercury and Jupiter in scientific notation. Mercury's diameter is about 3.0 x 10^3 miles, while Jupiter's diameter is about 8.8 x 10^4 miles. To find the difference, we subtract the diameter of Mercury from the diameter of Jupiter:

Jupiter's diameter - Mercury's diameter = 8.8 x 10^4 miles - 3.0 x 10^3 miles

To subtract these numbers in scientific notation, we first convert them to have the same exponent:

Jupiter's diameter - Mercury's diameter = 8.8 x 10^4 miles - 0.3 x 10^4 miles

Now we subtract the coefficients:

Difference = (8.8 - 0.3) x 10^4

Difference = 8.5 x 10^4 miles

So, the difference in diameters expressed in scientific notation is 8.5 x 10^4 miles.

Answer 2

8.5 × 10^4 miles

Step-by-step explanation:

To find a difference, you must subtract.

8.8 × 10^4 - 3.0 × 10³ =

= 8.8 × 10^4 - 0.3 × 10^4

= 8.5 × 10^4

Answer: 8.5 × 10^4 miles
