Answer:
(i) 8.5 × 10^-12
(ii) 9.42 × 10^-12
(iii) 602 × 10^15
(iv) 8.37 × 10^-9
(v) 3.186 × 10^10
Step-by-step explanation:
(i) 0.0000000000085
= 0.0000000000085 × 10^12/10^12
= 8.5/10^12
= 8.5 × 10^-12
(ii) 0.00000000000942
= 0.00000000000942 × 10^12/10^12
= 9.42/10^12
= 9.42 × 10^-12
(iii) 6020000000000000
= 602 × 10^15
(iv) 0.00000000837
= 0.00000000837 × 10^9/10^9
= 8.37/10^9
= 8.37 × 10^-9
(v) 31860000000
= 3.186 × 10^10
