1) Let's evaluate that expression (9234556)+(3.4×10^9)
(9234556)+(3.4×10^9) Removing the Parentheses
9234556+3.4×10^9 Rewriting the 2nd number (in Standard form)
9234556 +34000,000,000 Adding them up
Finally, the sum of those numbers is equal to 34,009,234,556
Rewriting it as scientific notation 3.40x 10^9 Since the rest of the number (the second addend: 9234556) is too tiny in comparison to 3.4 x 10^9 (the first addend).
