Answer:
a = 2/3
Step-by-step explanation:
A cube root is the same as a 1/3 power. The square of that gives a 2/3 power.
a = 2/3

<em>Additional comment</em>
You can see the relationship between a root index and an exponent if you consider what the root means.
Consider a cube root, for example. When you cube the root, you get the original number:
(∛x)·(∛x)·(∛x) = x
Now, let's write the root as a power of x: x^a.
(x^a)·(x^a)·(x^a) = x . . . . . where x^a = ∛x
We know this product is ...
x^(a+a+a) = x^(3a) = x^1
This tells us that ...
3a = 1 ⇒ a = 1/3
That is, ∛x = x^(1/3).
Of course an n-th root is multiplied by itself n times to get the original number, so the corresponding exponent is x^(1/n).
it is 1/2 because it is greater
Answer:
I think this is the correct answer.
Answer:
Q1) y= 2
Q2) y= 4
Step-by-step explanation:
Q1) If you sub in x as -1, 2 to the power of -1 is 0.5. You always solve the power first, not the multiplication. So then you do 0.5 times 4 and you get 2.
Q2) If you sub in x as 0, anything to the power of 0 becomes 1. 2 to the power of 0 is 1. Then you do the multiplication, 4 times 1 = 4
(3x +2)-2
-2(3x) -2( +2) Distribute the -2
-6x - 4
20B - 16
/4 divide out a greatest common factor
4(5b - 4)
