a_(1)=-(2^(0))/(3)times(3)/(5)+(5)/(2)=(3)/(5)quad x(1)/(3)

-(3)/(5)times(3)/(5)+(5)/(2)-(3)/(5)times(1)/(6)

Using appropriate properties find -(2)/(3)times(3)/(5)+(5)/(2)-(3)/(5)times(1)/(6)

Using appropriate properties find : (2)/(3) xx (3)/(5) + (5)/(2) - (3)/(5) xx(1)/(6)

The image of the line (x-1)/(3)=(y-3)/(1)=(z-4)/(-5) in the plane 2x-y+z+3=0 is the line (1)(x+3)/(3)=(y-5)/(1)=(z-2)/(-5) (2) (x+3)/(-3)=(y-5)/(-1)=(z+2)/(5) (3) (x-3)/(3)=(y+5)/(1)=(z-2)/(-5) (3) (x-3)/(-3)=(y+5)/(-1)=(z-2)/(5)

(2^((1)/(3))xx5^((2)/(3)))/(2^(-(2)/(3))xx5^(-(1)/(3)))

[((-2)/(-3))times(1)/(5)]times((-2)/(7))=((-2)/(-3))times[(1)/(5)times((-2)/(7))]
