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

HELP ME ASAP
We do exponents like this a^b
and multiply like this a * b
anyway

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

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
Thank you I got 100. And I understand. Thank you so much, wish you the best!
Sure, I can help you with these practice questions. Let's go through each question step by step.
1. Write the expression using exponents.
To write the expression 3 x 3 x 3 x 3 using exponents, we can replace the repeated multiplication with an exponent. The base of the exponent will be the number being multiplied, which is 3 in this case. The exponent will be the number of times it is being multiplied, which is also 3. So, the expression can be written as 3^4. Therefore, the answer is B. 34.
3. Is there an error in writing 5 x 5 x 5 as 3'5? If so, what is it?
Yes, there is an error in writing 5 x 5 x 5 as 3'5. The correct way to represent the repeated multiplication of 5 x 5 x 5 is by using an exponent. So, it should be written as 5^3, not 3'5. Therefore, the answer is none of the given options.
4. Apply the order of operations to simplify the expression.
To simplify the expression 2'4 - 8 x 2 ÷ 4, we need to follow the order of operations, which is parentheses, exponents, multiplication and division (from left to right), and lastly addition and subtraction (from left to right).
First, let's simplify the exponent 2'4. This means we need to multiply 2 by itself 4 times. So, 2'4 is equal to 2 x 2 x 2 x 2, which is equal to 16.
Now, substituting the value into the expression, we have: 16 - 8 x 2 ÷ 4.
Next, we multiply and divide from left to right: 16 - 16 ÷ 4.
Dividing 16 by 4 equals 4: 16 - 4.
Lastly, we subtract: 16 - 4 = 12.
Therefore, the answer is B. 12.
5. Apply the order of operations to simplify the expression.
To simplify the expression 5 + 2'3 x 2, we again need to follow the order of operations.
First, let's simplify the exponent 2'3. This means we need to multiply 2 by itself 3 times. So, 2'3 is equal to 2 x 2 x 2, which is equal to 8.
Now, substituting the value into the expression, we have: 5 + 8 x 2.
Next, we multiply: 5 + 16.
Lastly, we add: 5 + 16 = 21.
Therefore, the answer is 21.
I hope this helps! If you have any further questions, feel free to ask.
