Question

verify (-20)×[15+(-5)]=[(-20)×15]+[(-20)×(-5)]​

Answer 1

${\huge{\underbrace{\bf{\pink{Answer}}}}}$

⠀

LHS :

☞ (- 20) × [15 + (-5)]

☞ (-20) × (10)

☞ -200

⠀

⠀

RHS :

☞ [(-20) × 15] + [(-20) × (-5)

☞ [-300] + [100]

☞ -200

⠀

⠀

So, L.H.S = R.H.S = ( -200)

Answer 2

Answer:

$\huge{\underline{\underline{\purple{A}\pink{n}\green{s}\blue{w\red{e}\orange{r}}}}}$

to prove :-(-20)×[15+(-5)]=[(-20)×15]+[(-20)×(-5)]

LHS :

= (- 20) × [15 + (-5)]

= (-20) × (10)

=-200

RHS :

=[(-20) × 15] + [(-20) × (-5)

= [-300] + [100]

= -200

So, L.H.S = R.H.S = ( -200)
