Exponents

The difference between brackets and no brackets.

-2⁶=-64    -(2)(2)(2)(2)(2)(2)=-64

(-2)⁶=64    (-2)(-2)(-2)(-2)(-2)(-2)=64

If the negative is inside the brackets and the exponent is a even number. The answer then will be positive.

If the negative is outside the brackets and the exponent is even  or odd the answer is negative.

Two rabbits doubles every hour. How many rabbits will there be after 6 hours?

The answer is 64 because 2×2=4×2=8×2=16×2=32×2=64
