Write the following numbers in the usual form: 4.83 × 10^7 , 4.5 × 10^4

Question

Write the following numbers in the usual form:

(i) 4.83 × 107

(ii) 3.02 × 10-6

(iii) 4.5 × 104

(iv) 3 × 10-8

(v) 1.0001 × 109

Answer 1

(i) 4.83 × 10000000 = 4830000000

= 48300000.00

∴ Hence ,the usual form is 48300000

(ii) Hence, the usual form is 0.00000302

(iii) 4.5 × 10000 = 450000

= 45000.0

∴ the usual form is 45000

(iv) Hence, the usual form is 0.00000003

(v) 1.0001 × 1000000000 = 10001000000000

= 1000100000.0000

∴ the usual form is 1000100000
