Fill in the blanks so that the equality holds
`723xx36+723xx64=723xx(______)`

Answer

To solve the equation \( 723 \times 36 + 723 \times 64 = 723 \times (______) \), we can follow these steps:

### Step 1: Identify the common factor
We notice that both terms on the left side of the equation have a common factor of \( 723 \).

### Step 2: Factor out the common term
We can factor out \( 723 \) from both terms:
\[ 723 \times 36 + 723 \times 64 = 723 \times (36 + 64) \]

### Step 3: Simplify the expression inside the parentheses
Now, we need to calculate \( 36 + 64 \):
\[ 36 + 64 = 100 \]

### Step 4: Write the final equation
Now we can substitute back into the equation:
\[ 723 \times (36 + 64) = 723 \times 100 \]

### Conclusion
Thus, the blank can be filled with \( 100 \):
\[ 723 \times 36 + 723 \times 64 = 723 \times (100) \]

### Final Answer
The answer is \( 100 \).
