Answer 1

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`
