Question

I HAVE DOUBTED THIS QUESTION...
PLEASE MAKE ME UNDERSTAND GUYS!​

Answer 1

${\huge{\red{\boxed{\overline{\underline{\answer}}}}}}$

$\tt = > \sqrt{a \sqrt{b \sqrt{c \sqrt{d} } } }$

$\tt = > \sqrt{a \sqrt{b \sqrt{c \times d { \frac{}{} }^{ \frac{1}{2} } } } }$

$\tt = > \sqrt{a \sqrt{b \times c {}^{ \frac{1}{2} } \times d {}^{ \frac{1}{4} } } }$

$\tt = > \sqrt{a \times {b {}^{ \frac{1}{2} } \times c {}^{ \frac{1}{4} } \times d {}^{ \frac{1}{8} } } }$

$\tt = > a {}^{ \frac{1}{2} } \times b {}^{ \frac{1}{4} } \times c {}^{ \frac{1}{8} } \times d {}^{ \frac{1}{16} }$

Hence ,

answer = (A)

HOPE IT'S HELPFUL.....:)
