Question

Which is a perfect square?

Answer 1

`6^(2)`

Explanation:

`6^(1)` = 6
`√(6)` = 2.45 (NOT a perfect square)

`6^(2)` = 36
`√(36)` = 6 (perfect square)

`6^(3)` = 216
`√(216)` = 14.7 (NOT a perfect square)

`6^(5)` = 7776
`√(7776)` = 88.18 (NOT a perfect square)

If the answer ends with a decimal, they are not perfect squares.

Answer 2

I believe it's 6^2.

Step-by-step explanation: 6^2 is the same as 6 times 6. Here's a tip, if you see a 2 as an exponent, you can also say x squared. X to the power of 2 is the same as x squared.
