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:

Step-by-step explanation:
When you do that operation, the <em>y</em>'s become an exponential.
