1. The problem is to simplify the expression where all "x" symbols represent multiplication. 2. Since "x" means multiplication, replace all "x" with the multiplication operator \(\times\). 3. For example, if the expression is \(3x4x5\), rewrite it as \(3 \times 4 \times 5\). 4. Multiply step-by-step: \(3 \times 4 = 12\). 5. Then multiply the result by 5: \(12 \times 5 = 60\). 6. So, the simplified result of \(3x4x5\) is \(60\). 7. This method applies to any expression where "x" means multiplication: just replace and multiply sequentially.
