Answer

# Answer: ## Question 6 $\frac{1}{2}$ ## Question 7 $1.17\times 10^{5}$ # Explanation: ## Question 6 ### Step1: Simplify each part $2^{-2}=\frac{1}{2^{2}}=\frac{1}{4}$, $\sqrt[3]{8^{2}}=\sqrt[3]{(2^{3})^{2}} = 2^{2}=4$ ### Step2: Calculate the product $2^{-2}\cdot\sqrt[3]{8^{2}}=\frac{1}{4}\times4 = 1$ ## Question 7 ### Step1: Multiply the coefficients $2.6\times4.5 = 11.7$ ### Step2: Add the exponents of 10 $10^{-4}\times10^{8}=10^{-4 + 8}=10^{4}$ ### Step3: Write in scientific - notation $11.7\times10^{4}=1.17\times10^{5}$
