The square of (LG6) under LG2 + Lg3 + root sign + lg6-2lg6 =? lg2+lg3+√(lg6)^2+lg6-2lg6= Inside the root sign is (LG6) ^ 2 + lg6-2lg6

The square of (LG6) under LG2 + Lg3 + root sign + lg6-2lg6 =? lg2+lg3+√(lg6)^2+lg6-2lg6= Inside the root sign is (LG6) ^ 2 + lg6-2lg6


LG2 + Lg3 + square of (LG6) under root sign + lg6-2lg6
= lg6+|lg6|-lg6
=|lg6|
Because LG6 > 0, the result = LG6
Analysis: LG2 + Lg3 = LG6
Square of (LG6) under root sign = | LG6 |
lg6-2lg6 =-lg6
