Question

6. Find the product, using suitable properties :
(i) 46 (-48) + (-48) X (-36)
(iii) 25 × (-5) (-4)
(U) - 37 x (102)
(vii) 18 [100 - 2]
(ix) (-57) (-19) + 57
(ii) 16 x 39 x (-25)
(iv) 15 x (-25) × (- 4) (-10)
(ii) 625 X (- 35)+(- 625) x 65
(viii) (-27) ×(-29)​

Answer 1

Step-by-step explanation:

(i) 46 (-48) + (-48) X (-36)

= - 2,208 + 1728 = - 480

(iii) 25 × (-5) (-4) = - 125 * - 4 = 500

(U) - 37 x (102) = - 3,774

(vii) 18 [100 - 2] = 18 [ 98 ] = 1,764

(ix) (-57) (-19) + 57 = 1083 + 57 = 1,140

(ii) 16 x 39 x (-25) = 15,600

(iv) 15 x (-25) × (- 4) (-10)

= - 375 * - 4 * - 10 = 1500 * - 10 = - 15000

(ii) 625 X (- 35)+(- 625) x 65

= - 21,875 + ( - 40,625 )

= - 21,875 - 40,625 = - 62,500

(viii) (-27) ×(-29) = 783
