Answer:

The angles are 23° , 67°

Step-by-step explanation:

Let one angle be 'x'.

Its complement = 2*x + 21 = 2x + 21

x + 2x + 21 = 90°

3x + 21 = 90

Subtract 21 from both sides,

3x = 90 - 21

3x = 69

Divide both sides by 3,

x = 69/3

x = 23°

Its complement = 2*23 + 21

= 46 + 21

= 67°

Two complementary angles are 67 and 23

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:

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