Answer:
1/3
Step-by-step explanation:
(1/3)^2x(1/3)^-1
so, we can write this as:
1/3 x 1/3 x 3/1
if calculated by cutting, the answer is 1/3
There is also an easier way to do this,
(1/3)^2 x (1/3)^-1
as the bases are same, the powers will be added.
2+(-1)
2-1
=1
so,
(1/3)^1 or 1/3
Answer:
She should order 12 pizzas.
Step-by-step explanation:
5 pizza for every 20 students gives us the ratio 5:20.
5/20 = 0.25 = the amount of pizza each student gets.
If there are 48 students, you would just multiply 0.25 * 48 to get your answer.
They can be equal if the absolute value of b is 1.
