What is (c3)4?
| c7 | |
| 4c3 | |
| c12 | |
| 3c4 |
To raise a term with an exponent to another exponent, retain the base and multiply the exponents:
(c3)4A tiger in a zoo has consumed 66 pounds of food in 6 days. If the tiger continues to eat at the same rate, in how many more days will its total food consumtion be 143 pounds?
| 8 | |
| 13 | |
| 7 | |
| 11 |
If the tiger has consumed 66 pounds of food in 6 days that's \( \frac{66}{6} \) = 11 pounds of food per day. The tiger needs to consume 143 - 66 = 77 more pounds of food to reach 143 pounds total. At 11 pounds of food per day that's \( \frac{77}{11} \) = 7 more days.
a(b + c) = ab + ac defines which of the following?
distributive property for division |
|
commutative property for division |
|
commutative property for multiplication |
|
distributive property for multiplication |
The distributive property for multiplication helps in solving expressions like a(b + c). It specifies that the result of multiplying one number by the sum or difference of two numbers can be obtained by multiplying each number individually and then totaling the results: a(b + c) = ab + ac. For example, 4(10-5) = (4 x 10) - (4 x 5) = 40 - 20 = 20.
