Answer:

Positive exponent means that the decimal point will move right side according to the value of exponent.

Negative exponent means that the decimal point will move left side.

8a) 8.3 x $10^{5}$

So,

8.3 x $10^{5}$= 830000

b) 1.0039 x $10^{11}$ = 100390000000

c) 3.2 x $10^{-9}$ = 0.0000000032

9) 1st mass= 4.98 x $10^{21}$ = 4980000000000000000000

2nd mass = $10^{19}$ = 10000000000000000000

Ratio = 4980000000000000000000 : 10000000000000000000

        = 498 : 1
