# Small looking integrals have really big solutions

Calculus Level 3

$\large \int _{ 0 }^{ 1 }{ \frac { { ( 1 -16{ x }^{ \frac { 1 }{ 4 } } ) }^{ 2 } }{ { ( { 2 }^{ 8 }\ x ) }^{ \frac { 7 }{ 8 } } } \, dx }$

If the integral above can be written as $$\frac{a}{b}$$ for positive coprime integers $$a, b$$. Find $$a + b$$.
