Answer:
C
Step-by-step explanation:
First things first, we need to simplify (8^2)^-4. When a number is raised to a power, and the result of that is raised to another power, the two powers can be multiplied together to simplify. In this case, 2 * -4 = -8, so the question is asking how 8^-8 can be written.
8^-8 is the same as multiplying 8 8s together, and then finding the reciprocal (put it into a fraction where the original number is the denominator and 1 is the numerator).
Therefore, the 1 over the 8 8s multiplied together is the correct answer.
Answer:
$7
Step-by-step explanation:
a) First let's organize the information:
The cage cost $40
two bowls cost the same
the total was $54
b) Put it as an equation
40+x+x= 54
c) we will subtract 54-40 and get 14
d) divide 14 by 2 and get 7 for the cost of each bowl.
Hope you understand it ;)
