Answer 1

Step-by-step explanation:

${16}^{ - \frac{1}{4} } \times \sqrt[4]{16} \\ \\ = ({2}^{4} ) {}^{ - \frac{1}{4} } \times {16}^{ \frac{1}{4} } \\ \\ = {2}^{4 \times ( - \frac{1}{4}) } \times ({2}^{4} ) {}^{ \frac{1}{4} } \\ \\ = {2}^{ - 1} \times {2}^{1} \\ \\ = {2}^{ - 1 + 1} \\ \\ = {2}^{0} \\ \\ = 1 \\ \\ \\ using \: \: formula \: \: \sqrt[n]{x} = {x}^{ \frac{1}{n} } \\ \\ ({x}^{m} ) {}^{n} = {x}^{m \times n} \\ \\ {x}^{m} \times {x}^{n} = {x}^{ m+n } \\ \\ {x}^{0} = 1$
