When you multiply numbers with the same base and exponents, you just add the exponents together. In the case of the first question:
*
=
When dividing, subtract the exponents instead, and when there's an exponent outside the parentheses the way it is on the 3rd question, multiply them together.
Hope this helps! :)

Step-by-step explanation:
Given
per ride
Required
Explain the inverse function
First, we calculate the function
Let x represents the number of rides
So:
For the inverse function, we have:
Swap x and y
Make 3y the subject
Make y the subject
Replace y with the inverse function
The above is to calculate the number of rides; given the amount paid
The number of purple marbles in the bag are; 201 purple marbles
<h3>How to work out fraction of bar model?</h3>We are told that Two-fifths of the marbles are green, and the rest are purple.
A) The image attached shows the bar model where the shaded parts denote the purple marble while the unshaded parts denote the green marbles.
B) We are told that there are 134 green marbles.
If the total number of marbles are x. Then;
(2/5)x = 134
x = 134 * 5/2
x = 335 marbles
Thus;
Purple Marbles = (3/5) * 335 = 201 purple marbles
