Question

Which one does not belong? Identify the number that does not belong with the other three. Explain your reasoning using math vocabulary |-8|      square root of 64            8 to the power of zero             2 to the power 3

Answer 1

| -8 | refers to the absolute value of negative eight, which equals eight.

The square root of 64 is the number which, when multiplied by itself, equals 64. Since 8*8 = 64, the answer here is also eight.

8 to the power of 0 equals one. The rule is that any number raised to the power of zero equals one.

2 to the power of three means 2*2*2 which equals eight.

So the answer that does not belong is 8 to the power of zero, which equals one. All of the other answers equal 8.
