Question

Which expressions are equivalent to 2 to the power of 5 / 6 to the power of 5
1. 1/3
2. 3 to the power of -5
3. (-4) to the power of -5
4. 2 to the 5th power times 6 to the -5 power

Answer 1

Answer:

2. 3 to the power of -5

4. 2 to the 5th power times 6 to the -5 power

Step-by-step explanation:

(2⁵)/(6⁵)

(2/6)⁵

(1/3)⁵

(3^-1)⁵

3^(-5)

(2/6)⁵

2⁵ × (6^-1)⁵

2⁵ × (6^-5)

Answer 2

Steps to solve:

2^5/6^5

~Apply exponent rules

(1/3)^5

1^5/3^5

~Simplify

1/243

Now, we can solve for each option.

Option 1:

1/3 ≠ 1/243

This is incorrect.

Option 2:

3^-5 = 1/243

This is correct.

Option 3:

-4^-5

-1/4^5

-1/1024 ≠ 1/243

This is incorrect.

Option 4:

2^5 * 6^-5

2^5 * 1/6^5

2^5/6^5

1^5/3^5

1/243 = 1/243

This is correct.

Therefore, the correct answers are options 2 and 4.

Best of Luck!
