Question

Verpfy the following
18 × [7+(-3) ] = [ 18 X 7)+(18× _3​

Answer 1

Answer:

By using distributive law

ax(b+c)  = axb + axc

a) 18 x[7+(-3)] = 18x7  + 18 x (-3)

     18 x 4          = 126 - 54

         72     =  72     so it is true

b) -21 x [-4 + (-6)] = -21 x -4  + -21 x -6

     -21 x -10          = 84  +  126

            210             = 210     so this is also true   (- x - = +  & - x + = -)
