Answer:
We can have several equivalents.
It can be 1/784, 28^(-2), or 1/ (28^2)
Step-by-step explanation:
4^(-2) * 7^(-2) = (4*7)^(-2) = 28^(-2)
or 1 / (28^2) is another equivalent.
4^(-2) * 7^(-2) = 28^(-2)
4^(-2) * 7^(-2) = = 1/784
(a) 64
divide 16 by .25 and you will get 64
(b) 34
multiply 40 by .85
8000*.1=800 so the answer is 1/10 or .1
Answer is: 1 2/3
