Question

if 2 X + 3 Y is equal to 13 and X Y is equal to 6 then find the value of 8 x cube + 27ycube​

Answer 1

Answer:

535537

Step-by-step explanation:

XY = 2×3

2X + 3Y = (2×2) + (3×3) = 4+9 = 13

[ (8x)^3 ] + [ (27y)^3 ]

= (512x^3) + (19683y^3)

Put in the values of x and y

(512×8) + (19683×27) [Cube of 2 = 8 & Cube of 3 = 9]

4096 + 531441

ANSWER = 535537
