Question

Using suitable properties evaluate the following:-
(i) 8 x 53 x (-125)
(ii) 26 x (-48) + (-48) x (-36)
(iii) 15 x (-25) x (-4) x (-10)

Answer 1

Answer:

(i). 8×53 × (-125)

=. 424 × (-125)

= -53,000

(ii). 26× (-48) + (-48) × (-36)

=. -1248 + (-48) × (-36)

=. -1248 - 48 × (-36)

=. -1248 - (-1728)

=. -1248 + 1728

=. 480

(iii) 15× (-25) × (-4) × (-10)

=. -375 × 160

=. -60,000

Answer 2

Answer:

mark me as brainlist!!

Step-by-step explanation:

$8 \times 53 \times ( - 125) \\ = 424 \times ( - 125) \\ = - 53000 \\ a(b \times c) = (a \times b) \times c \\ = 8 \times 53 \times ( - 125) \\ = 8 \times ( - 125 \times 53 \\ = 8 \times ( - 125 \times 53) \\ = 8 \times ( - 6625) \\ = 53000 \\ hence \: the \: required \: answer \: is \: \\ - 53000$

2 ) 26 x (-48) + (-48) x (-36) = - 62500

3 ) 15 x (-25) x (-4) x (-10)= - 15000

I hope helpful you!
