6. Alex says he can find the product for \( (3 \times 5) \times 2 \) by solving \( 3 \times(5 \times 2) \). Is Alex correct? Explain.

Write the following in expanded form. A. \( 2 \times 10+8 \times 1+1 \times \frac{1}{10}+7 \times \frac{1}{100}+7 \times \frac{1}{1,000} \) B. \( 2 \times 10+8 \times 0+1 \times \frac{1}{10}+7 \times \frac{1}{100}+7 \times \frac{1}{1,000} \) C. \( 2 \times 10+8 \times 0+1 \times \frac{1}{1,000}+7 \times \frac{1}{100}+7 \times \frac{1}{100} \) D. \( 2 \times 10+8 \times 1+1 \times \frac{1}{1,000}+7 \times \frac{1}{100}+7 \times \frac{1}{10} \)

Find the value of \( \sqrt[3]{-64} \) .

Write the following in expanded form. A. \( 1 \times 100+6 \times 10+8 \times 1+9 \times \frac{1}{1,000}+4 \times \frac{1}{100} \) B. \( 1 \times 100+6 \times 10+8 \times 0+9 \times \frac{1}{1,000}+4 \times \frac{1}{100} \) C. \( 1 \times 100+6 \times 10+8 \times 0+9 \times \frac{1}{10}+4 \times \frac{1}{100} \) D. \( 1 \times 100+6 \times 10+8 \times 1+9 \times \frac{1}{10}+4 \times \frac{1}{100} \)

Write the following in expanded form. A. \( 1 \times 100+4 \times 10+8 \times 1+6 \times \frac{1}{1,000}+3 \times \frac{1}{100}+4 \times \frac{1}{10} \) B. \( 1 \times 100+4 \times 10+8 \times 1+6 \times \frac{1}{10}+3 \times \frac{1}{100}+4 \times \frac{1}{1,000} \) C. \( 1 \times 100+4 \times 10+8 \times 0+6 \times \frac{1}{10}+3 \times \frac{1}{100}+4 \times \frac{1}{1,000} \) D. \( 1 \times 100+4 \times 10+8 \times 0+6 \times \frac{1}{1,000}+3 \times \frac{1}{100}+4 \times \frac{1}{10} \)
