Simplify cube root of 7 / fifth root of 7 a. 7 to the power of 1 over 5 b. 7 to the power of 8 over 15 c. 7 to the power of 5 over 3 d. 7 to the power of 2 over 15

Option D. is the answer.

Step-by-step explanation:

we have to simplify the cube root of

=

=

=

=

Therefore, Option D. 7 to the power of 2 over 15 is the answer.

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%
