## Ashy98 one year ago Can someone help me with 2 questions?

1. Ashy98

Simplify open parentheses x to the 2 third power close parentheses to the 4 fifths power

2. Ashy98

A.) $x^\frac{ 2 }{ 5 }$ B.) $x^\frac{ 2 }{ 15 }$ C.) $x^\frac{ 8 }{ 15 }$ D.) $x^\frac{ 22 }{ 15 }$

3. Ashy98

Simplify 64 to the negative 1 third power A.) −4 B.) negative 1 over 4 C.) 1 over 4 D.) 4

4. Directrix

Is this the first problem: |dw:1443900793845:dw|

5. Directrix

Look at the "raising a power to a power" rule on the attachment.

6. Directrix

Ashy98 What does this equal: 2/3 times 4/5

7. Ashy98

8/15

8. Directrix

If this --> Q 2 A? means is the answer to question 2 the option A, then no. Let's finish the first question and then move to the second, okay?

9. Ashy98

okay

10. Directrix

8/15 is correct for the exponent on number 1. |dw:1443901228270:dw|

11. Directrix

Agree?

12. Ashy98

yes

13. Directrix

Simplify 64 to the negative 1 third power |dw:1443901341366:dw|

14. Directrix

64 to the negative 1/3 power does NOT mean -1/3 times 64. ---------------- What is 6 times -(1/3) = ?

15. Ashy98

-2?

16. Directrix

Yes. |dw:1443901600194:dw|

17. Directrix

Last step: What is 2 raised to the -2 power? Hint: the answer is not -4 becase 2 to the -2 power does not mean to multiply 2 by -2 :)

18. Directrix

On the chart I uploaded, look for the negative exponent rule.

19. Directrix

Question?

20. Directrix

No. |dw:1443901809575:dw|

21. Ashy98

ohh okay i did that wrong thank you!!!

22. Directrix

The negative exponent is not the sign of the base of the expression. It tells you that the expression belongs in a denominator.

23. Directrix

You are welcome.
