Q5Verify the following:(a) 18 × [7 + (–3)] = [18 × 7] + [18 × (–3)]​

Answer 1

Step-by-step explanation:

$18 × [7 + (–3)] = [18 × 7] + [18 × (–3)]$

18 x [7+ (-3) ] = [ 18 x 7 ] + [18 x (-3)]

18 × [7 + (–3)] = [18 × 7] + [18 × (–3)]

18 × [4] = [18 × 7] + [–54]

18 × [4] = 126 –54

72=72

LHS=RHS

hence verified!

(b) (–21) × [(– 4) + (– 6)] = [(–21) × (– 4)] + [(–21) × (– 6)]

(–21) × (-10) = 84 +126

210 = 210

LHS = RHS

Answer 2

Answer:

$\huge{ \red {\tt{18 × [7 + (–3)] = [18 × 7] + [18 × (–3)]}}}$

$\huge\fbox{ \fbox{\fbox\fcolorbox{cyan}{maroon}{ \huge \green {\tt{18 × [4] = [18 × 7] + [–54]}}}}}$

$\huge{\fbox{\fbox{ \huge\fcolorbox{black}{cyan}{ \color{grey}{18 × [4] = 126 –54}}}}}$

${ \red{ \tt{72=72}}}$

LHS=RHS

hence verified!
