8×1013

8×10^13 is a large positive integer commonly written in scientific notation as eight times ten to the thirteenth power. In decimal form it equals 80,000,000,000,000, or eighty trillion. The factorization 8×10^13 can be written as 2^16 × 5^13, since 10^13 = 2^13 × 5^13.

Note on interpretation: if the expression were intended as 8×1013 with 1013 interpreted as a plain integer (not scientific notation), the result would be 8,104. The standard use of the form 8×10^13 denotes a magnitude, not a simple concatenation of digits.

Applications and context: quantities expressed as 8×10^13 are typical for describing orders of magnitude in science. For example, 8×10^13 seconds is about 2.54 million years, illustrating how such a scale can arise in geology or astrophysics. If used as a distance in meters, 8×10^13 m is roughly 535 astronomical units, placing it in the outer reaches of the solar system. As a numerical value, 8×10^13 can also appear in discussions of counts, masses, or other measurements where a precise integer is less important than the overall scale.

Summary: 8×10^13 denotes eighty trillion, expressed compactly via scientific notation. It is a convenient way to convey very large quantities in mathematics and the sciences, while its exact meaning depends on the chosen units.
