Simplify the following using distributive property;
(i). 25(19+25) (ii). 512(259+325) (iii). 89(112+29)
The distributive property state that a×(b+c)=(a×b)+(a×c) ......(i)
(i) Given expression 25(19+25)
Applying rule of equation(i), we get
25(19+25)=(25×19)+(25×25)
=245+425
=(2×5)+(4×9)225
=10+36225
∴25(19+25)=46225
(ii) Given expression 512(259+325)
Applying the rule of equation(i), we get
512(259+325)=(512×259)+(512×325)
=125108+16060
=(125×5)+(160×9)540
=625+1440540
=2065540
∴512(259+325)=413108
(iii) Given expression 89(112+29)=(89×112)+(89×29)
=8818+1681
=(88×9)+(16×2)162
=792+32162
=824162
∴89(112+29)=824162
