HELP ME PLEASE THIS IS JUST PART 2 PLEASE ANSWER THE PRACTICE QUESTIONS. Anyway, please help me with this

Question

1. Write the expression using exponents.
3 x 3 x 3 x 3
A. 33***(small three)
B. 34
C.43
D. 35
I already found the second question's answers so moving on.
3. Is there an error in writing 5 x 5 x 5 as 3'5? If so, what is it?
A. There is no error, because 5 x 5 x 5 = 3'5
B.There is no error, because 5 x 5 x 5 = 5'15
C. There is no error, because 5 x 5 x 5 = 25'2
D.There is no error, because 5 x 5 x 5 = 5'3
4. Apply the order of operations to simplify each expression.
2'4-8 x 2 ÷4=
A.0
B.12
C. 16
D.4
Apply the order of operations to simplify each expression.

Answer 1

We do exponents like this a^b
and multiply like this a * b
anyway
============================
1. Write the expression using exponents.
3 x 3 x 3 x 3
A. 33***(small three) NO, there are 4 of them
B. 34
C.43
D. 35
3*3*3*3 = 3^4
I already found the second question's answers so moving on.
=================================================
3. Is there an error in writing 5 x 5 x 5 as 3'5? If so, what is it?
A. There is no error, because 5 x 5 x 5 = 3'5
B.There is no error, because 5 x 5 x 5 = 5'15
C. There is no error, because 5 x 5 x 5 = 25'2
D.There is no error, because 5 x 5 x 5 = 5'3

5*5*5 is NOT 3^5. It is 5^3
=========================================
4. Apply the order of operations to simplify each expression.
2'4-8 x 2 ÷4=
A.0
B.12
C. 16
D.4
******************
2'4-8 x 2 ÷4= 2^4 - 8 * 2 / 4
= 16 - 4 = 12
**********************
Apply the order of operations to simplify each expression.
5 + 2'3 x 2 = 5 + 2^3 * 2
= 5 + 8*2
= 5 + 16
= 21
