Pyramids were the first engineering marvel seen in history.
The reason why is that Pyramids are the oldest constructions known to archeologists, scientists, and historians. There are pyramids, like the Egyptian Pyramids in Giza, Cairo, that had been dated from thousands of years before Christ. Modern research affirms that the pyramids could be older than mainstream science has established.
Architects admire the mathematics and engineering knowledge of ancestral Egyptians who were able to build those magnificent pyramids without the technology needed to build them. Even today, those pyramids are impossible to build. That is why these pyramids remain a mystery.
It believe it's the Pythagorean Theorem, named after Pythagoras in ancient Greece 2,500 years ago
For the answer to the question above,
<span>If you know how to write numbers in exponential notation, that would give you the answer right away.
