Answer:

y = -9 or y = -3 depending on what this problem is asking.

Explanation:

If it is y times 3 on the left:

Divide both sides by 3 to get y by itself

If it is y to the third power on the left

Take the cube root of both sides

Answer:answer is -3

Step-by-step explanation:since its the square root of three it can bt +3 because a negetive with a negtive with a negetive is a postive so the first is wrong the third will equal to 81 so that the wrong answer and same goes with the last one so the one that makes the most sense is the second one
