Question

verify x+ (y+z) = (x+y)+z gor following values of x,y and z. x=-3/5, y=-7/10z=-8/15​

Answer 1

Answer:

yes x+(y+z) = (x+y)+z

Step-by-step explanation:

x= -3/5 y = -7/10 and z = -8/15

LHS                                                              

x+(y+z)

-3/5+(-7/10+-8/15)

-3/5+(-7/10-8/15)

= -55/30

RHS

(x+y)+z

(-3/5+-7/10)+-8/15

(-3/5-7/10)-8/15

= -55/30              hence proved, LHS=RHS
