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

$(a ^ n) ^ m = a ^ {n * m}$

We must rewrite the following function:

$f (x) = 7 (\frac {1} {2})^{3x}}$

Using the mentioned property we have:

$f (x) = 7 ((\frac {1} {2}) ^ 3) ^ x$

Solving the operation within the parenthesis we have:

$f (x) = 7 (\frac {1 ^ 3} {2 ^ 3}) ^{ x}\\f (x) = 7 (\frac {1} {8})^{x}$

Thus, the correct option is option B

Let u = <-9, 4>, v = <8, -5>. Find u - v. <br> URGENT

Pie

To subtract vectors, you simply have to subtract correspondent coordinates.

So, if you have

$u = \langle u_1,\ u_2,\ldots u_n\rangle ,\quad v = \langle v_1,\ v_2,\ldots v_n\rangle$

the subtraction is simply

$u-v = \langle u_1-v_1,\ u_2-v_2,\ldots u_n-v_n\rangle$

So, in your case, we have

$\langle-9,4\rangle-\langle 8,-5\rangle=\langle -9-8, 4+5\rangle=\langle -17,9\rangle$
