1st is power to call a friend. If you don't know the
answer you can ask your group mates for the answer.
2nd is power to substitution. You have a chance to
change the player.
3rd power would be power to block. You have a
chance to block the other group so that they cannot
answer the question.

17. Exponent
Exponent is a symbol above and to
the right of mathematical expression
to indicate the operation of raising to
a power.

19. Any nonzero number raised to a power of 0 is
equal to 1.
Zero Exponents

20. Negative Integral Exponents

23. Rational exponents (also called fractional exponents).
Review: Rational numbers (fractions) are real
numbers that can be written in the form a/b, where a
and b are integers and b ≠ 0. Hence, they can be
whole numbers, fractions and mixed numbers, and
decimals, together with their negative images.
Rational Exponents
