Ok, then I'll take it! (See solution #2, solution #1 and some variations thereof is what I already had).

1)

√{5||[5(ϕ + 2)/10^5] + ϕ + 2}

[ a||b = ab/(a + b) ]

001:# ϕ
002:# 002
003:+ 
004:# 005
005:SDR 005
006:RCL× Y
007:# 005

→ 1.902160583101354

2)

√{ϕ + 2 + [0.2 + 20000/(ϕ + 2)]⁻¹}

001:# 002
002:SDR 001
003:# ϕ
004:RCL+ L
005:# 200
