147 = 1 + 23 + 4 + 5 + 6 × 7 + 8 × 9
147 = 9 × 8 + 7 × 6 + 5 + 4 + 3 + 21
147 = 0^6 − 1^8 + 2^4 − 3^9 + 4^7 + 5^5 + 6^3 + 7^0 + 8^1 + 9^2
147 divides 50^2 - 1.
147 = (11 + 1)(1+1) + 1 + 1 + 1
147 = (2 + 22/2)2 − 22
147 = 3 + (3 + 3) × (33 − 3)
147 = 4 × (4 + 4) + 4 + 444/4
147 = 147 = 5 × 5 + (555 + 55)/5 = ((5)!+((.5*55)-.5))
147 = 66 + 6 × 66/6
147 = 7 × (7 + 7 + 7)
147 = 8 × (8 + 8) + 8 + 88/8
147 = 9 + 9 + 9 + 9 + 999/9
\( 147^2 = 58^2 + 46^2 + 127^2 \)
\( 147^2 = 94^2 + 113^2 + 2^2 \)
\( 147^2 = 97^2 + 82^2 + 74^2 \)
\( 147^2 = 58^2 + 94^2 + 97^2 \)
