Let a=3 2 and b= 1 5^ 1 / 6 6 . If x, y R are such that gathered 3 x+2 y= _a(18)^ 5 4 2 x-y= _b( 1080 ) gathered and then 4 x+5 y is equal to . ________.

Step-by-step solution

aligned & 3 x+2 y= _ 3 2 (3 2 )^ 5 2 = 5 2 & 6 x+4 y=5 (1) aligned 2 x-y= _ 1 5^ 1 / 6 6 (5^ 1 6 6 )^3=-3 array ll & 2 x-y=-3 .....(2) & equation (1) -(2) & 4 x+5 y=8 array
