Rewrite in simplest rational exponent form x^1/2*X^1/4
jasenka [17]

Answer:

\sqrt[4]{x^3}

Step-by-step explanation:

First, let's examine our original statement.

x^{\frac{1}{2} }\cdot x^{\frac{1}{4}}

Using exponent rules, we know that if we have x^a \cdot x^b, then simplified, the answer will be equivalent to x^{a+b}.

So we can simplify this by adding the exponents \frac{1}{2} and \frac{1}{4}.

Converting  \frac{1}{2} into fourths gets us \frac{2}{4}.

\frac{2}{4} + \frac{1}{4} = \frac{3}{4}.

So we now have x^{\frac{3}{4}}.

When we have a number to a fraction power, it's the same thing as taking the denominator root of the base to the numerator power.

Basically, this becomes

\sqrt[4]{x^3}. (The numerator is what we raise x to the power of, the denominator is the root we take of that).

Hope this helped!

Jami is trying to model the movement of a tire. In order to properly model the movement, she is going to focus on the movement o
USPshnik [31]

From the given data it is clear that the amplitude of the wave will be 9 inches.

It is also clear that the speed of rotation, ω, will be: \omega=\frac{2\pi}{T}=\frac{2\pi}{8}=\frac{\pi}{4}

Now, it is given that the nozzle is on the right side of the tire and that position is going to be treated as the equilibrium position, the tire is then rotated such that the nozzle goes up at the beginning of the rotation. This condition is possible only when we have a Sine (Sin) function.

Thus, our final answer can be arrived as:

Amplitude\times Sin(\omega t)

9\times sin(\frac{\pi}{4}t) =9sin(\frac{\pi}{4}t)

Thus, out of the given options, option B is the correct answer.

8u/u^2-18u+81 subtract 72/u^2-18u+81
Karo-lina-s [1.5K]
Your question is:
\frac{8u}{u^2-18u+81} -\frac{72}{u^2-18u+81}
Then, the above formula equate:

\frac{8u-72}{u^2-18u+81}
Factor out 8 from the numerator we get:
\frac{u-9}{u^2-18u+81}
Factorization of the denominator:
\frac{u-9}{(u-9)^2}
Simplifying the numerator and the denominator by (u-9) we get:
\frac{1}{(u-9)}
