Answer:

1

Explanation:

The given expression is

$\frac{2^{(11)/(2) }* 2^(-7)* 2^(-5)}{2^3* 2^{(1)/(2) }* 2^(-10)}$

Recall and use

a^m* a^n=a^(m+n)

$\frac{2^{(11)/(2) -7-5}}{ 2^{3+(1)/(2) -10}}$

$\frac{2^{-(13)/(2)}}{ 2^{-(13)/(2)}}$

Same bases are dividing, so we write one base and subtract the exponent.

$2^{-(13)/(2)+(13)/(2)}$

2^0=1
