#=30 #

Explanation:

Division operation within 1st bracket(or Parentheses ) is done first
#6 + 3[(cancel12^3 / cancel4) + 5] #
#=6 + 3[3 + 5] #
Now operation on third bracket( Parentheses ) gives
#=6 + 3*8 #
Now operation of multiplication comes,it gives
#=6 + 24 #
Then operation of addition gives the result
#=30 #
#PEMDAS->#"Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction". Rule is thus followed in order
