Which expression is equivalent to (x^4/3 x^2/3)^1/3?

KATRIN_1 [288]

Answer: $x^{\frac{2}{3} }$

Step-by-step explanation:

We have several properties of exponents in use here. The two that are used are:

$(x^{a})(x^{b}) = x^{a + b}$ (Exponents with the same base that are being multiplied together can have the exponents added)

$(x^{a})^{b} = x^{(a)(b)}$ (A base raised to a power, and then raised to another power means that you can multiply the exponents to get the same result as doing inside operations and then outside operations)

Let's apply it!

First, let's simplify what's inside the parenthesis.

$x^{\frac{4}{3} } x^{\frac{2}{3} }$ (Remember, they have the same base of "x", so we can add the exponents)

$x^{\frac{4}{3} + \frac{2}{3} }$ = $x^{\frac{6}{3} }$ = $x^{2}$

Now we have $(x^{2})^{\frac{1}{3} }$ . Let's use the second rule.

$(x^{2})^{\frac{1}{3} }$ = $x^{\frac{2}{3} }$

Hope this helps! :^)

4x+y=14, 6x-3y=3 is the question

fomenos

Answer:

if you are being asked what the values of the x and y variables are, x=5/2 and y=4

Step-by-step explanation:

In order to solve this problem you will want to isolate one of the two variables in both equations.

I isolated the y variable in both equations so you have:

4x+y=14, when you isolate the y variable, you will get: y=-4x+14

6x-3y=3, same procedure isolate y: 6x-3=3y, now simplify so you only have y: 2x-1=y.

Now that you have the two equations which a common variable, solve them by making the two equations equal to each other like so:

-4x+14=2x-1, now you want to have all the x variable terms on one side and all the constants on the other, you will add "4x" to each side of the equal sign and then add "1" to each side to leave you with: 15=6x

now divide both sides by 6 to obtain your x value: x=15/6 simplifies to 5/2

then plug your x-value into one of the two equations we made earlier:

y=2x-1

y=2(5/2)-1

y=5-1

y=4

now you have calculated the values of your x and y values

Solve r/n + t = 4v for r

lana [24]

Since r is being divided by N, we need to multiply both sides by N.
We are left with R + T = 4v/n
Now, we subtract T from each side. The equation is now R = 4V/N - T
We have now solved for R.
