Question

Verify a(b)=a+b for the following value of a and b.
(i). a=28,b=1
(ii). a=118,b=125
(iii). a=75,b=84
(iv). a=28,b=1

Open in App
Solution

a(b)=a+b

(i) a=21,b=18 then

LHS=21(18)=21+18=39
RHS=21+18=39

(ii) a=118,b=125 then

LHS=118(125)=118+125=243
RHS=118+125=243

(iii) a=75,b=84 then

LHS=75(84)=75+84=159
RHS=75+84=159

(iv) a=28,b=1 then

LHS=28(1)=28+1=29
RHS=28+1=29

Hence verified.
