What is the value of \(82^3 + 3(82^2)(18) + 3(82)(18^2) + 18^3 \)? (No calculators! And see if you can do it in your head!)
I think it is 100,000

wait so can you tell me how did you do it? Something like (x+y)^3 right? and x=82, y=18

Well I simplified it into (82+18)^2 and I used variables like a=18 and b=82
