Question

Is the absolute value of
I pi^2 - 10 I
the same thing minus the abs. value signs?
Just imagine the pi^2 to be the pi symbol squared.

Answer 1

Lets start even more basic than that.
|7-8| = |-1| = 1
7-8 = -1

|3-10| = |-7| = 7
3-10 = -7

|10-3| =|7|=7
10-3 = 7

|20 - 3| = |17| = 17
20-3 = 17

Do you see a pattern?
Now if you let pi = 3.14 then pi sqaured is 9.869604401
Now in your case if you subtract 10 from pi squared you end up with a negative number. Look at the examples above. What happens to a negative number if you take the absolute value of it?
You should be able to answer your question now.

Answer 2

No.

The value of pi is about 3.14. If you square that number, you get 9.8596. It will never get to 10, no matter how far you stretch the decimal.

So, if you subtract 10 from 9.___, you get a negative number, no matter what. The absolute value will always be positive. So no, they aren't the same.

Answer 3

When I went to school we used 3.1416 for the value of pi unless told to use 3.14. It figures out to infinity for it has no end in site.

In Star Trek the TV series the computer was ask to figure the value of pi to it's final number in order to keep the computer busy because there is no ending value to it.

Answer 4

10 - pi^2 and
pi^2 - 10

Answer 5

No

pi^2 < 10 so

pi^2 - 10 < 0 and |pi^2 - 10| > 0

Answer 6

The answer to the question is no.You evaluate the inside equation first then take the absolute value. The absolute value is removing a negative sign if it's a negative result. If it's positive, then you just take the value, no change.

Answer 7

|pi^2 - 10|
= |9.869694401 - 10|
= |-0.1303955989|
= 0.1303955989

Answer 8

|pi^2 - 10| = +/- ( pi^2 - 10)

Answer 9

pi^2 = 9.86960
Without the absolute bars this would be -.130396
With the absolute bars this would be +.130396
The answer is NO!

Answer 10

According to my calculator, π²<10 so no. It would be the same as 10-π²
