18×[12+(-3)]=18×12+18×(-3)

18×[9]=216-54

172=172

Answer 2

Step-by-step explanation:

LET 18*[12+(-3)] BE LHS

AND 18*12+18*(-3)RHS

IDENTITY USED HERE:

a(b+c)=a×b+a×c

solvin LHS:

18*[12+(-3)]

=18*9

=162

SOLVING RHS:

18*12+18*(-3)

=216+(-54)

=162

LHS=RHS

HENCE:-

18x[12+(-3)]=18x12+18x(-3) proved
