Rewrite in simplest radical form: x^4/5 / x^1/3 into a√x^b
mrs_skeptik [129]

Answer:

\sqrt[15]{x^7}

Step-by-step explanation:

If we have the expression

\frac{x^{\frac{4}{5}}}{x^{\frac{1}{3}}}, we have to think about exponent rules.

If we have a^b \div a^c, then the value will be equal to a^{b-c}.

So \frac{x^{\frac{4}{5}}}{x^{\frac{1}{3}}} simplified will be x^{\frac{4}{5} - \frac{1}{3}}

Converting \frac{4}{5} and \frac{1}{3} into fifteenths (lcm) gets us \frac{12}{15} - \frac{5}{15} = \frac{7}{15}.

We can convert x^{\frac{7}{15}} into a radical by taking the denominator root of x to the numerator.

\sqrt[15]{x^7}.

Hope this helped!

Write a real world problem that you would represent with the equation 4x+5=37.
AURORKA [14]
Bob was 5 feet off the ground. He travels 4 feet every single second. How long will it take for him to reach 37 feet?

4x + 5 = 37

4x + 5 (-5) = 37 (-5)

4x = 32

4x/4 = 32/4

x = 8

It will take Bob ~8 seconds to reach 37 feet*

One of the roots of the equation x2−5x+q=0 is 2. Find the other root and the value of the coefficient q.
pishuonlain [190]

Answer:

q=6

Step-by-step explanation:

A root can be plugged in for X, so 2(2)-5(2)+q=0. This means -6+q=0. We can now even them out and know q=6
