MAT 221Week One Discussion OneDr Dutta and Classmates,My birthdate is July 5 1960, so I will incorporate the following integers(whole numbers). aequals the birth month 7b equals the day of my birth in the negative form - 5cequals the two-digit year 60I will use the algebraic expressions for a, b, cthat I created above for parts 3-5 of this discussion. The variablesrepresented in the equation are aand band their exponentsof 3 on each of them. Since 7 is my birth month that variable will represent aand variable bis -5. Due to the exponents, the integers were raised to the 3rdpower anything minus a negative it becomes a positive, and then you will get the definitive answer.A.) a3 - b3 73 – (-53)343 – (-125)343+125Answer 468When performing the second expression, the variablesused were also aand b; 7 representing aand - 5 representing b. In the first portion of the equation two negatives will equal a positive and then I did the multiplication and squaring.
