1. The problem is to simplify the expression $X \times 30 \times X \times 15$. 2. We start by recognizing that multiplication is associative and commutative, so we can rearrange the terms: $$X \times X \times 30 \times 15$$ 3. Next, multiply the constants: $$30 \times 15 = 450$$ 4. Now the expression is: $$X^2 \times 450$$ 5. Therefore, the simplified form is: $$450X^2$$ This means the product of $X$ times 30 times $X$ times 15 equals $450X^2$.
