Simplify:

(i) We have,

2 × 10³ = 2 × 10 × 10 × 10

= 2 × 1000

= 2000

(ii) We have,

7² × 2² = 7 × 7 × 2 × 2

= 49 × 4

= 196

(iii) We have,

2³ × 5 = 2 × 2 × 2 × 5

= 8 × 5

= 40

(iv) We have,

3 × 4⁴ = 3 × 4 × 4 × 4 × 4

= 3 × 256

= 768

(v) We have,

0 × 10² = 0 × 10 × 10

= 0 × 100

= 0

(vi) We have,

5² × 3³ = 5 × 5 × 3 × 3 × 3

= 25 × 27

= 675

(vii) We have,

2⁴ × 3² = 2 × 2 × 2 × 2 × 3 × 3

= 16 × 9

= 144

(viii) We have,

3² × 10⁴ = 3 × 3 × 10 × 10 × 10 × 10

= 9 × 10000

= 90000
