What is the equivalent of 243 to the power of (2/5)

1 answer:

6 0

(243)^(2/5) = ?
---
The 5 in the denominator means "take the 5th root".
The 2 in the numerator means "square".

---

Taking the 5th root first you get:
(243)^(2/5) = 3^2
Now squaring gives you
3^2 = 9

So the answer is 9.

Hope this helps :)

HELP PLEASE Solve for x: x - 8 = 3x - 2 -3 -2 3 1

creativ13 [48]

Answer:

x=3

Step-by-step explanation:

You add the eight to both sides, leaving x on the left and making the -2 a 6 on the right.

Now you have x= 3x-6

Add the six to the right, giving you 6+x=3x

Subtract the x from the left and right. you get 6=2x

Divide 6 by 2 to get x.

Fynjy0 [20]

Answer:

Functions are linearly dependent (are not linearly independent.)

Step-by-step explanation:

Remember that two functions f(x), g(x) and h(x) are said linearly independent on an interval I if the only solution to the equation

$\alpha f(x)+\beta g(x)+\omega h(x)=0, \ \text{for all } x\in I$

is the trivial one: α = 0, β = 0, ω = 0. If they are not linearly independent, they are called linearly dependent.

Now, let f(x), g(x) and h(x) be the functions:

$f(x)=e^{3x}+\cos(5x),$

$g(x)=e^{3x}-\cos(5x),$

$h(x)=\cos(5x).$

Then, letting α = 1, β= -1 and ω = -2, we see that:

$\alpha f(x)+\beta g(x)+ \omega h(x)=e^{3x}+\cos(5x)-e^{3x}+\cos(5x)+2\cos(5x)=0.$

Hence, the functions f(x), g(x) and h(x) are not linearly independent, or equivalently, are linearly dependent.
