To find the distance from Earth to the sun, we need to add the distance from Venus to the sun and the additional distance of 2.6×10^7 miles.
The distance from Venus to the sun is 67,000,000 miles.
Now, convert 67,000,000 to scientific notation:
67,000,000 = 6.7 × 10^7 miles.
Now add the distance from Venus to the sun (in scientific notation) to the additional distance (also in scientific notation):
\[ 6.7 \times 10^7 + 2.6 \times 10^7 = (6.7 + 2.6) \times 10^7 = 9.3 \times 10^7. \]
Thus, the distance from Earth to the sun is:
\[ \text{Distance from Earth to the sun} = 9.3 \times 10^7 \text{ miles}. \]
So, the answer is 9.3 × 10^7 miles.
