b)500
c)400
d) 600​

Answer 1

Answer: ANSWER IS 500

Step-by-step explanation:

(361)^3 + (139)^3/ (361)^2 - 361 ×139 + (139)^2

so wht u hv 2 do is expand the first term by using the identity a^3+b^3=(a+b)(a^2-ab+b^2)

s v wll get (361+139)(361^2-361x139+139^2)

by executing this formula to the down denominator-(361)^2 - 361 ×139 + (139)^2...we wll get like terms and cut all the like terms...

atlast v would b left wid 361+139 which is equal to 500

:ANSWER IS 500
