which statement explains mario’s error?

Last option

Step-by-step explanation:

1. According to the properties of exponents, you have that:

2. Then, he must simplify the expression as following:

3. Therefore, as you can see, should have also applied the negative exponent to 4 to get

The correct answer option is He should have also applied the exponent -3 to 4 to get .

Step-by-step explanation:

The following expression was to be simplified by Mario:

Given this expression, we need to apply this rule on it in order to simplify:

So we would get:

This would be the right simplification for the given expression but by looking at Mario's work shown, we can conclude that:

He should have also applied the exponent -3 to 4 to get .

2 over 5

step-by-step explanation:

the 2: 3 ratio is the length of the ac segment to the cb segment total length. this implies that the ratio between segment ac length and segment ab length is 2: 5. point c is 2/5 from a to b, so the required fraction is 2/5.
