The simplified expression is 3.833 x 10⁷ g
Explanation:
Given expression;
3.88 x 10⁷ g - 4.701 x 10⁵ g
The expression above is simplified as follows;
= (3.88 x 100 x 10⁵ )g - ( 4.701 x 10⁵) g
= (388 x 10⁵ )g - ( 4.701 x 10⁵) g
= (388 - 4.701 ) x (10⁵ )g
= 383.299 x 10⁵ g
In standard form, the simplified expression can be expressed as;
= (3.83299 x 100 x 10⁵) g
= 3.83299 x 10⁷ g
= 3.833 x 10⁷ g
Therefore, the simplified expression is 3.833 x 10⁷ g

Cell can be connected in parallel by connecting like-polarity terminals of adjacent cells to each other. The voltage remains the same, but it can benefit the batteries in the two ways:
Increased Current: The current output in a parallel connection increases.
Increased Power: With the same current drawn as earlier, the connected n cells can power the system for n times as earlier
