The commutative property states that, when adding or multiplying numbers, the order in which they're added or multiplied does not matter. For example, 3 + 4 and 4 + 3 give the same result, as do 3 x 4 and 4 x 3.
Which of the following statements about exponents is false?
b1 = b |
|
b0 = 1 |
|
b1 = 1 |
|
all of these are false |
A number with an exponent (be) consists of a base (b) raised to a power (e). The exponent indicates the number of times that the base is multiplied by itself. A base with an exponent of 1 equals the base (b1 = b) and a base with an exponent of 0 equals 1 ( (b0 = 1).
What is \( \frac{21\sqrt{20}}{3\sqrt{5}} \)?
| 4 \( \sqrt{\frac{1}{7}} \) | |
| \(\frac{1}{4}\) \( \sqrt{\frac{1}{7}} \) | |
| 7 \( \sqrt{\frac{1}{4}} \) | |
| 7 \( \sqrt{4} \) |
To divide terms with radicals, divide the coefficients and radicands separately:
\( \frac{21\sqrt{20}}{3\sqrt{5}} \)
\( \frac{21}{3} \) \( \sqrt{\frac{20}{5}} \)
7 \( \sqrt{4} \)
