✓(36x38x42x44 + 36) =
6✓(38x42x44 + 1) =
6✓(44(40 - 2)(40 + 2) + 1) =
6✓(44(40^2 - 4) + 1) =
6✓(44x1600 - 175) =
6(5)✓(44x64 - 7) =
30✓(2816 - 7) =
30✓(2809) = 30 x 53 = 1590

(40-2)(40+2)(40-4)(40+4)+36=(40^2-4)(40^2-16)+36=40^4-20*40^2+10^2=(40^2-10)^2, Thus, ?=40^2-10=1590.

1590

[@martinphipps2]

sqrt(36x38x42x44+36)
= 6sqrt(38x42x44+1)
= 6sqrt[38(43-1)(43+1)+1]
= 6sqrt[38(43x43-1)+1]
= 6sqrt[38(129+1720-1)+1]
= 6sqrt[38x1849-37]
6sqrt70225
= 6x265 = 1590
