Explain how to solve the equation: x^4/x^2

Mathematics
1 answer:
Margarita [4]3 years ago
8 0

Answer:

x^2

Step-by-step explanation:

A better word than "solve" would be "simplify."  The word "equation" does not apply here, since there is no = sign and thus no equation.

The applicable rule here is


x^a / x^b = x^(a-b), so x^4/x^2 = x^(4-2) = x^2 (answer in simplest form)

Answer: x ≈ 18 ft

Step-by-step explanation:

We will use our trig knowledge to solve this.

The man is standing 10 ft away, but we also need to add the 5 ft shadow as well as that is a point on our triangle.

We can set up a simple trig equation of: tan(50) = x/15

x being the height of the lamppost.

Now we solve.

tan(50) = 1.1918

1.1918 *15 = x

x = 17.876

Now round to the nearest foot.

x ≈ 18 ft
