Question is in picture need help asap
Andrej [43]
The given expression is:

\sqrt[4]{ 9^{ \frac{1}{2}x } }

4th root is equivalent to raising the expression to power \frac{1}{4}. So, re-writing the expression by converting radical to exponent:

( 9^{ \frac{1}{2}x } )^{ \frac{1}{4} } \\  \\ 
= 9^{ \frac{1}{8}x }

Therefore, the given expression simplifies to 9^{ \frac{1}{8}x }

kherson [118]

Answer:  4

<u>Step-by-step explanation:</u>

To fit the maximum amount of people in one row, you would have 3 couples and 1 single = 7 parents.

If we continue the maximum amount of people for 7 rows, we get 49 parents seated.

Since a total of 54 parents are seated, that leaves 54 - 49 = 5 parents remaining to be seated in the last row.  These parents can be seated as 2 couples and 1 single. If you put the single at the end of the row, there will be 4 seats between the couple and the single.

Couple, Couple, Open, Couple, Couple, <u>Open</u>, <u>Open</u>, <u>Open</u>, <u>Open</u>, Single
