Answer» Q.1) a + ( b + c ) = ( a + b ) + c ➭ Substitute the VALUES, -» -25+ [20+ (-10) = [(-25) +20] + (-10) Solve the RHS with BRACKETS first, Solve the LHS with brackets first, -» -25 + 10 = [(-25) +20] + (-10) Add the integers in LHS, -» -15= [(-25) +20] + (-10) -» -15=(-5)+ (-10) Add the integers in RHS, -» -15= -15 Comparing both SIDES, LHS = RHS Thus, verified. ------------------------------------- 2) a × (b + c) = a × b + a × c Solution: Substitute the values, -» -25 x [20+ (-10)] = (-25) × 20 + (-25) × (-10) Solve the LHS with brackets first, -» -25 x 10 = (-25) 20+ (-25) (-10) MULTIPLY the integers, -» 250 = (-25) x 20 + (-25) × (-10) Solve the RHS using BODMAS rule, -» -250 = -500 + 250 Add the integers, -» -250 = -250 Comparing both sides, LHS = RHS Thus, verified. hope it was helpful to you |
