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

Which of the following sets could be the sides of a right triangle?
Genrish500 [490]

Answer:

None of the above

Step-by-step explanation:

None of the answer choices are even triangles, let alone right triangles. The sum of the two smaller sides isn't larger than the bigger side on any of the triangles, which means that they cannot be closed.
