Answer:

Step-by-step explanation:

Given :

Total number of people : 36

Ratio of people who prefer red to blue

Red : Blue = 3 : 9 = 1 : 3

according to the ratio, for every 4 people, 1 prefers red and 3 prefers blue.

Expressed mathematically:

People who prefer blue = 3/4 of the total number of people

In our case, total number is 36 hence,

People who prefer blue (and hence the number of blue pens he should order),

= 3/4 x 36 = 27

Simplify the expression.<br> (x 3/2)6

Sliva [168]

For this case we must simplify the following expression:

$(x ^ {\frac {3} {2}}) ^ 6$

We have that by definition of properties of powers that is fulfilled:

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

Then, rewriting the expression:

$x ^ {\frac {3 * 6} {2}} =\\x ^ {\frac {18} {2}} =\\x ^ 9$

Answer:

$(x^{\frac{3}{2}})^6=x^9$
