Please help me with these I really don’t understand them a step by step would be very much appreciated

729, 7, 100000000, 81000000, 1/4

Step-by-step explanation:

Question 1:

Remember that the viniculum represents subtraction with exponents!

In that case, we can simplify the expression 3^8 * 3^4/3^2 * 3^4:

3^6 = 729. So 729 is our answer.

Question 2:

Using this property, we can simplify to 7^1 or 7 as our answer.

Question 3:

Power to power means multiplacation. So (10^4)^2 is equivalent to 10^8 = 100000000.

Question 4:

Applying this property again gives 3^4 * 10^6. 10^6 * 81 = 81000000.

.

Question 5:

Applying the property used in question one,  we can simplify to 2^-1 * 2^-1.

Since 2^-1 is equivalent to 1/2, we are multiplying 1/2 * 1/2. That equals our final answer of 1/4.

the answer is c)8
