Find the value of the following expressions using properties of whole numbers. Name the property used (i) 25 x 20 x 5 (ii) 4,259 x 92 + 8 x 4,259 (iii) 5,386 x 188 - 88 x 5,386 (iv) 8,135 x 169 - 8,135 x 69
Answers
Step-by-step explanation:
Xylem is the specialised tissue of vascular plants that transports water and nutrients from the plant–soil interface to stems and leaves, and provides mechanical support and storage. The water-conducting function of xylem is one of the major distinguishing features of vascular plants.18-Oc
(i) 25 × 20 × 5
= 25 × (20 × 5)
= 25 × 100
= 2500
By Using Associative Property
(ii) 4,259 × 92 + 8 × 4,259
= (4,259 × 92) + (4,259 × 8)
= 4,259 × (92 + 8)
= 4,259 × 100
= 4,25,900
By Using Distributive Property over Addition
(iii) 5,386 × 188 - 88 × 5,386
= (5,386 × 188) - (5,386 × 88)
= 5,386 × (188 - 88)
= 5,386 × 100
= 5,38,600
By Using Distributive Property over Subtraction
(iv) 8,135 × 169 - 8,135 × 69
= (8,135 × 169) - (8,134 × 69)
= 8,135 × (169 - 69)
= 8,135 × 100
= 8,13,500
