Consider the product \( 1 \times 2 \times 3 \times 4 \times \ldots \times 30 \). Determine the largest value of \( k \) such that \( 3^{k} \) is a factor of this product.

a) \( \left(\frac{1}{2}+\frac{2}{3}\right)^{2}= \)

3) \( \sqrt{8} \cdot \sqrt{8} \)

Convert the measurement to the nearest hundredth. (Feel free to use a calculator on this problem) \( 54 \mathrm{f} / \mathrm{sec}=\square \mathrm{mph} \) Submit Question
