49-(1/4)÷49(1/4)={[(4×49)-1]/4}÷49(1/4)
                          ={[(4×49)-1]/4}×(4/49)
                          =(196-1)/49
                          =195/49

Answer:

\frac{1}{7}

Step-by-step explanation:

Given : (49)^{-\frac{1}{4}} \div (49)^{\frac{1}{4}}

To Find :simplify

Solution:

(49)^{-\frac{1}{4}} \div (49)^{\frac{1}{4}}

\frac{(49)^{-\frac{1}{4}}}{(49)^{\frac{1}{4}}}

Property : \frac{a^m}{a^n}=a^{m-n}

So,  (49)^{-\frac{1}{4} -\frac{1}{4}}

(49)^{-\frac{2}{4}}

(49)^{-\frac{1}{2}}

(7^2)^{-\frac{1}{2}}

(7)^{-1}

\frac{1}{7}

Hence (49)^{-\frac{1}{4}} \div (49)^{\frac{1}{4}} =\frac{1}{7}
