8 0

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

What about the inequality sign like < = >
docker41 [41]
The < and > signs mean lesser and greater than. = means equal(s). The signs will always look like they are eating the bigger value. For example:
12<29
Twelve is lesser than twenty-nine, or
29>12
Twenty-nine is greater than twelve.
An equation uses an equal sign
12+8=20
When you're using all of them, it can look like this:
1<n<29
This is read as "one is lesser than n which is lesser than 29". These can be used to determine the lengths of the sides of a triangle. In this case, n must be between 1 and 29 for it to be the side of a triangle.
