163

163 is a Prime Number, Prime(38)

163 = 12 + 34 + 5 × 6 + 78 + 9

163 = 9 × 8 + 76 + 5 + 4 + 3 + 2 + 1

163 = 0^4 − 1^8 + 2^6 − 3^9 + 4^7 + 5^5 + 6^3 + 7^2 + 8^1 + 9^0

163 = 1^2 + 9^2 + 9^2

163 divides 58^3 - 1.

163 = (1 + 1) × (11 − 1 − 1)⁽¹⁺¹⁾ + 1

163 = ((2⁽²⁺²⁾ + 2)² + 2)/2

163 = (3 + 3) × 3³ + 3/3

163 = 4 × (44 − 4) + 4 − 4/4

163 = 55 × 5 − (555 + 5)/5

163 = 6 × (6 × 6 − 6) − 6 − 66/6

163 = 7 + (7 + 7) × (77 + 7/7)/7

163 = 88 + 8 × 8 + 88/8

163 = 9 × (9 + 9) + 9/9

163 = \( \binom {8}{0} + \binom {8}{1} + \binom {8}{2} + \binom {8}{3} + \binom {8}{4} \)

\( \exp{ \pi \sqrt{163}} \approx 640320^3 + 744 \)

163 = \( (4^4 + \binom {8}{4} )/2 \)

\( 163 \approx 2^9 / 163 \)
