CPM Homework Help : MC1 Problem 9-71

In a previous course you may have learned that $8^{3} = 8 · 8 · 8 = 512$ . Rewrite the following expressions using multiplication and then calculate the final value for each of them (as shown for $8^{3}$ above).

$10^{4}$
Hint (a):
Each exponent (the smaller number to the top right of the $10$ ) represents another $10$ by which to multiply.
Answer (a):
$\left(10\right)\left(10\right)\left(10\right)\left(10\right) = 10{,}000$

$5^{3}$
Hint (b):
What is the exponent in this problem?
That will be the number of fives to multiply together.
Answer (b):
$\left(5\right)\left(5\right)\left(5\right) = 125$

$(\frac { 1 } { 2 })^2$
Hint (c):
Remember, when multiplying fractions, you simply multiply the numerators together and denominators together.

$\left(–2\right)^{3}$
Hint (d):
The product of three negative numbers is a negative number.
