1. The problem is to simplify the expression $444f44 + 5t5$. 2. This expression contains variables $f$ and $t$ and numbers concatenated with them, which suggests multiplication: $444f44$ means $444 \times f \times 44$ and $5t5$ means $5 \times t \times 5$. 3. Calculate each term separately: - $444f44 = 444 \times 44 \times f = 19536f$ - $5t5 = 5 \times 5 \times t = 25t$ 4. Now, add the two terms: $$19536f + 25t$$ 5. This is the simplified form of the expression since $f$ and $t$ are different variables and cannot be combined further. Final answer: $$19536f + 25t$$
