Answer:

ANSWER

(a) LHS =18×[7+(−3)]=18×4=72

RHS =[18×7]+[18×(−3)] =126+(−54)=72 (verified)

(b) LHS =(−21)×[(−4)+(−6)]=(−21)×(−10)=210

RHS =[(−21)×(−4)]+[(−21)×(−6)]=84+126=210 (verified)

Step-by-step explanation:

Given :

18×[7+(-3)]=[18×7]+[18×(-3)]

Concept :

Find the value of LHS (Left hand side and the value of RHS (Right hand side) .

After getting the value of both the side if the value will be same then the answer will get verified.

Solution :

Value of LHS -:

:\Rightarrow\tt{LHS=18\times[7+(-3)]}

(+)×(-)=-

:\Rightarrow\tt{LHS=18\times[7-3]}

:\Rightarrow\tt{LHS=18\times4}

:\Rightarrow\tt{LHS=72}

Value of RHS -:

:\Rightarrow\tt{RHS=[18\times7]+[18\times(-3)]}

:\Rightarrow\tt{RHS=126+(-54)}

:\Rightarrow\tt{RHS=126-54}

:\Rightarrow\tt{RHS=72}

So , LHS = RHS .

Hence , verified.....
