A comet is about 7.63 × 103 miles from Earth. Write this number in standard form.
Simora [160]

Answer:

7630

Step-by-step explanation:

We have that the distance of a comet from Earth is about 7.63*10³ .

This number is given in scientific notation.

We want to write this number in standard form.

Since we are multiplying by a power of 10, we move forward three times.

Therefore in standard form:

7.63 \times  {10}^{3}  = 7630
