To express the diameter of Earth, which is given as \(1.27 \times 10^7\) in standard form (not scientific notation), you can simply convert it by calculating the number it represents.
Calculating \(1.27 \times 10^7\):
\[ 1.27 \times 10^7 = 1.27 \times 10,000,000 = 12,700,000 \]
Therefore, the diameter of Earth in standard form is 12,700,000.
