The Problem
(1,234)² means 1,234 * 1,234; (1,234)³ means 1,234 * 1,234 * 1,234; and so forth. When
(1,234)²³ is completely multiplied out, what will the number be in the ones place?
Answer:
QV had an adequate explanation, so I am borrowing from hers:
4
4 x 4, 16
16 x 4, 64
64 x 4, 256
256 x 4, 1024
1024 x 4, 4096
Follow the pattern.
even exponents will end in 6, odd exponents will end in 4
