Hi there!

<u>Error 1</u>

<u />(3^3+3^2)^2\\= (3^5)^2<u />

The student added the exponents of 3³ and 3² and wrote 3⁵. This rule can only be applied to exponents with the same base that are being <em>multiplied</em>. 3³ and 3² were being added, not multiplied, so this rule can't be applied.

<u>Error 2</u>

<u />(3^5)^2\\= 3^7<u />

When a power has a power, we multiply them, not add. Here is the correct way of doing it:

(3^5)^2\\= 3^5^*^2\\= 3^1^0<u />

<u />

<u>Error 3</u>

3^7\\= 21

The student multiplied 3 and 7 to get 21, but 3⁷ actually means 3 multiplied by itself 7 times. The correct answer for this part would be 2187.

I hope this helps!

Answer:

1. (3^3 + 3^2)^2 actually equals (27 + 9)^2

which is the first mistake

2. (27 + 9)^2 does not equal (3^5)2, so (36)^2 does not equal 3^7

3. 3^7 DOES NOT EQUAL 21

Step-by-step explanation:

when you add powered numbers together, it does not multiply it, as your example:

1. (3^3 + 3^2)^2 actually equals (27 + 9)^2

which is the first mistake

2. (27 + 9)^2 does not equal (3^5)2, so (36)^2 does not equal 3^7

3. 3^7 DOES NOT EQUAL 21

Alexxandr [17]

Answer:

Undefined

Explanation:

When a line is vertical like that, the slope is undefined. If it was horizontal, then it would be zero. Positive slopes go in an upward right direction. Negative slopes go in a downward left direction.
