29

29 is a Prime Number. Prime(10)

29 = 12 + 34 + 5 + 67 − 89

29 = 9 − 87 + 65 + 43 − 2 + 1

29 = 0^6 − 1^7 + 2^9 − 3^8 + 4^1 + 5^5 + 6^2 + 7^4 + 8^3 + 9^0

29 = 2^2 + 5^2

29^2 = 20^2 + 21^2

29 = (1 + 1 + 1) × (11 − 1) − 1
= 22 + 2 + 2 + 2 + 2/2
= 3 + 3³ − 3/3
= 44 − 4 × 4 + 4/4
= 5 × 5 + 5 − 5/5
= 6 × 6 − 6 − 6/6
= 77 − 7 × 7 + 7/7
= 8 + (88 + 88 − 8)/8
= 9 + 9 + 99/9
