Question

simplify (4÷7)-5 × (7÷4)-7
​

Answer 1

Answer:

Answer:

(\frac{4}{7})^{2}

Step-by-step explanation:

Given : (\frac{4}{7})^{-5} \times (\frac{7}{4})^{-7}

To Find : Simplify

Solution:

(\frac{4}{7})^{-5} \times (\frac{7}{4})^{-7}

Property: a^{-x}=(\frac{1}{a})^x[/tex</p><p>So, [tex](\frac{4}{7})^{-5} \times (\frac{4}{7})^{7}

Property: a^x \times a^y = a^{x+y}

So, (\frac{4}{7})^{-5+7}

(\frac{4}{7})^{2}

Hence (\frac{4}{7})^{-5} \times (\frac{7}{4})^{-7} = (\frac{4}{7})^{2}
