Answer»

⟹\dfrac{\sqrt[4]{1250} }{ \sqrt[4]{2} }

⟹\dfrac{ {(1250)}^{ \frac{1}{4} } }{  {(2)}^{ \frac{1}{4} }  }

⟹{ (\dfrac{1250}{2}) }^{ \frac{1}{4} }

Now , 625×2 = 1250

⟹{ (625) }^{ \frac{1}{4} }

we KNOW :- 625= 5×5×5×5 = 5⁴

⟹{ (5 \times 5 \times 5 \times 5) }^{ \frac{1}{4} }

⟹{(  {5}^{4}  )}^{ \frac{1}{4} }

⟹{( 5) }^{ \frac{1}{4}  \times 4}

⟹5

Answer :- 5

Laws of EXPONENT :-

1)a^m \times a^n= {a}^{(m + n)}

2) {( {a}^{m})}^{n}   =  {a}^{mn}

3) {ab}^{n}  =  {a}^{n}  {b}^{n}

4) \frac{ {(a)}^{m} }{ {(a)}^{n} } = {a}^{m - n}

5) {a}^{ - b}  =  \frac{1}{ {a}^{b} }
