To solve the expression $(1.64 \times 10^4) + (7.28 \times 10^3)$, follow these steps:

Step 1: Rewrite each number in standard form

• $1.64 \times 10^4 = 16,400$
• $7.28 \times 10^3 = 7,280$

Step 2: Add the two numbers

$16,400 + 7,280 = 23,680$

Thus, $(1.64 \times 10^4) + (7.28 \times 10^3) = 23,680$.
