Question

What is the value of

Answer 1

Answer:

256/81

Step-by-step explanation:

The exact form is 256/81.

Answer 2

For this case we have that by definition of power properties:

$a ^ {- 1} = \frac {1} {a ^ 1} = \frac {1} {a}$

We have the following expression:

$(- \frac {3} {4}) ^ {- 4}$

We can rewrite it as:

$(- \frac {3} {4}) ^ {- 4} = \frac {1} {(- \frac {3} {4}) ^ {4}} = \frac {1} {\frac { 3 ^ 4} {4 ^ 4}} =$

Applying double c we have:

$\frac {4 ^ 4} {3 ^ 4} = \frac {256} {81}$
