Question

verify X into (y into z ) equal to (X into y ) into z if X equal to 3/-4 , y equal to-11/17 and z equal to -21/22​

Answer 1

Answer:

question :- X * (y*z) = (X*y) * z

Step-by-step explanation:

       3/-4 * -1/-1 = -3/4

=>  -3/4 * (-11/17 * -21/22) = (-3/4 * -11/17)  *-21/22

=>   -3/4 * (-1/17 * -21/2) = (-3/4 * -11/17)  *-21/22

=>   -3/4 * 21/34 = 3/68 * -21/2   (After simplifying and dividing) (here both

                                                   minus (-) sign  are canceled after multiplying)

=>   -63/136  = -63/136       (multiply both sides and the answers will be same)
