Step-by-step explanation:

i) \:  {(729)}^{ \frac{1}{6} }

=  {(3 \times 3 \times 3 \times 3 \times 3 \times 3)}^{ \frac{1}{6} }

=    \sqrt[6]{(3 \times 3 \times 3 \times 3 \times 3 \times 3)}

= <em><u>3 (Ans)</u></em>

ii) \:  {(64)}^{ \frac{2}{3} }

=  \sqrt[3]{ {64}^{2} }

=  \sqrt[3]{(64 \times 64)}

=  \sqrt[3]{ {2}^{12} }

=  {(2)}^{ \frac{12}{3} }

=  {2}^{4}

= <em><u>16 (Ans)</u></em>

iii) \:  {(243)}^{ \frac{6}{5} }

= {( \sqrt[5]{ {243} })}^{6}

=  {3}^{6}

= <em><u>729 (Ans)</u></em>

Liula [17]

Answer:

Equation: 8.5t+6.5=57.5

Solution: t=6

Step-by-step explanation:

Let be "t" the number of movie tickets bought by the group of friends.

According to the information given in the exercise, the price of each movie ticket is: $8.50.

Then, you can represent the amount (in dollars) the group of friends spent in movie tickets, with this expression:

8.5t

You know that one person spent $6.50, then the expression that represents the total amount (in dollars) the group of friends spent in food and movie tickets, is:

8.5t+6.5

Since that total amount spent is given in the exercise, you can write the following equation to determine how many tickets were bought:

8.5t+6.5=57.5

Finally, you can solve for "t" in order to find the solution of the equation. This is:

8.5t=57.5-6.5\\\\t=\frac{51}{8.5}\\\\t=6
