Question

verify the property x×(y+z)=x×y+x×z by taking -

Answer 1

Step-by-step explanation:

x= -3/7, y= 2/5, z= -7/4

L.H.S, x*(y+z)

(y+z) = (2/5+(-7/5))= -27/20

x*(y+z)= (-3/7) *(-27/20)

= 81/140

R.H.S, (x*y)+(x*z)

(x*y)= (-3/7)*(2/5)= -6/35

(x*z)= (-3/7)*(-7/4)=21/28

(x*y)+(x*z)= (-6/35)+(21/28)=81/140

L.H.S=R.H.S
