Hexadecimal Equations (Problem $6$ , Version $4$ )

$2^{(5)} = 2(2 + 1)(2 + 2)(2 + 3)(2 + 4) = 2(3)(4)(5)(6) = 720$

$4^{(3)} = 4(4 + 1)(4 + 2) = 4(5)(6) = 120$

$720 + 120 = 840$

$46^{(3)} = 46(46 + 1)(46 + 2) = 46(47)(48) = 103776$

$840 \times 103776 = 87171840$

$(4)_5 = 4(4 - 1)(4 - 2)(4 - 3)(4 - 4) = 4(3)(2)(1)(0) = 0$

$A = 10$

$F = 15$

$87171840F - 10$

$8 \times 16^8 + 7 \times 16^7 + 1 \times 16^6 + 7 \times 16^5 + 1 \times 16^4 + 8 \times 16^3 + 4 \times 16^2 + 0 \times 16^1 = 8 \times 4294967296 + 7 \times 268435456 + 1 \times 16777216 + 7 \times 1048576 + 1 \times 65536 + 8 \times 4096 + 4 \times 256 + 0 \times 16 = 36263003151 + 15 = 36263003166$

$36263003166 - 10 = 36263003156$
