Answer 2

Your Question:

Simplify

${x}^{ - 2} {y}^{5} \times {x}^{0} {y}^{ - 7}$

Solution:

${x}^{ - 2} {y}^{5} \times {x}^{0} {y}^{ - 7} \\ = \frac{1}{ {x}^{2} } {y}^{5} \times 1( \frac{1}{ {y}^{7} } ) \\ = \frac{1}{ {x}^{2} } \times \frac{1}{ {y}^{2} } \\ = \frac{1}{ {x}^{2} {y}^{2} } \\ = {(xy)}^{ - 2}$

Identities used

• ${x}^{0}=1$
• ${x}^{-m} = \frac{1}{{x}^{m}}$
