(1.6 × 10-19)(5.0 × 106) = c × 10d identify the missing numbers below to show the result of multiplying the numbers.

(3.5x1016) = 3556
and 
(2.2x1010) = 2222

As per question;
(3556)x(2222) = 10 a*b
By dividing both sides by "10"
we get
(3556)x(222.2) = a*b
or 
(355.6)x(2222) = a*b
by comparing both sides of the equation, 
we get that a = 3556  and b = 222.2
or 
a = 355.6 and b = 2222

A = 7.7 and B = 26

Step-by-step explanation:

Given expression,

 

According to the question,

By comparing,

A = 7.7

B = 26

the answer you are looking for ir A) 7.7 B) 26

In order to find the value of "a" and "b", first of all perform the multiplication in the parenthesis. 
Thus

(3.5x1016) = 3556
and 
(2.2x1010) = 2222

As per question;
(3556)x(2222) = 10 axb
By dividing both sides by "10"
we get
(3556)x(222.2) = axb
or 
(355.6)x(2222) = axb
by comparing both sides of the equation, 
we get that a = 3556  and b = 222.2
or
a = 355.6 and b = 2222
