Answer:

$3^{12}$

Step-by-step explanation:

$($ $3^{5}$ $)^{2}$

You multiply the exponents to get:

$3^{10}$

Then you divide it by $3^{-2}$

When dividing exponents, you subtract.

10 - - 2 = 12 so the exponent is 12.

That leaves us with:

$3^{12}$

What is the property and how are the exponents combined?

Answer:

x^15

Step-by-step explanation:

x^3 * x^2 (x^3)^2 x^6

-------------------------------

x^2

First I will use the power of powers x^a^b = x^(a*b)

x^3 * x^2 x^(3*2) x^6

-------------------------------

x^2

x^3 * x^2 x^(6) x^6

-------------------------------

x^2

Next we will use the multiplication rule x^a * x^b = x^(a+b)

x^(3 +2+6+6)

-------------------------------

x^2

x^(17)

-------------------------------

x^2

Next we will use quotient rule x^a / x^b = x^(a-b)

x^(17 -2)

x^15

An h = 135-ft tower is located on the side of a mountain that is inclined 32° to the horizontal. A guy wire is to be attached to

Vikentia [17]

Answer:

171 foot

Step-by-step explanation:

We are given that

Height of tower=135 ft

AC=55 ft

Let x be the length of shortest length of wire.

The angle of inclination of mountain with horizontal = $32^{\circ}$

The angle between sides AB and BC= $90+32=122^{\circ}$

Exterior angle is equal to sum interior angles of a triangle on the opposite sides .

We have to find the value of x.

We know that law of cosine

$c=\sqrt{a^2+b^2-2ab cos\theta}$

Substitute the values in the given formula we get

$x=\sqrt{(135)^2+(55)^2-2(135)(55)cos 122}$

$x=170.64 ft$

Hence, the length of wire needed=171 foot
