So this is a bit confusing. I don't know if you need me to solve them then simplify or just reduce them but I will try to write it anyways.
1.
For this, you can just multiply 3 by 5 which is 15 then place it as an exponent as

But if you need to solve it, you multiply 4 by itself 15 times which is107,3741,824 but I don't think thats what you are looking for but here it is anyways
I assume that it was the former that was the answer
Answer:
2. 
When dealing with negative exponents, you get one and divide by the base according to the exponent. It says -2⇒2 which means you divide 1 by 4, twice
1÷4÷4=.0625
Answer: .0625
3. 
Since its positive, you multiply by the base number (rather than divide if it was negative)
So it is 4×4×4=64
Answer: 64
4. 
Here, you just take what I did in step 3 and multiply by the base number according to the exponent
4×4×4×4×4×4×4×4=65,536
Answer: 65, 536
5. 
You do what you did in the previous steps but multiply the base 15 times
4×4×4×4×4×4×4×4×4×4×4×4×4×4×4=1,073,741,824
Answer: 1,073,741,824
If you don't know what to do, go and ask your teacher because he/she would know best on what to do :-)
Answer:
<h2>r = 10</h2>
Step-by-step explanation:
The equation of a circle in standard form:

(h, k) - center
r - radius
We have the equation:

Therefore we have
the center (0, 0)
radius r = 10
Answer:
Step-by-step explanation:
First, we need to find the y-intercept. The y-intercept is the intersection of the point on the y-axis. We can clearly tell that the y-intercept is 1. The slope is definitely 0 because it shows a straight line.
Hence, the equation is y = 1.
Please check out my graph to support my reasoning.
B. Compare independent variables
You can use substitution for this.
x+5 = 5x -11
Combine like terms
16=4x
Divide 4 on both sides to isolate the x
x=4
Plug x=4 to one of the equations
y= 4 +5
Combine like terms
y=9
So the answer is A. (4,9)
I hope this helps you out a bunch hun :)
