and I have one more question,sorry.
I3I2^4+I68^2+3.10I
(The I(s) stand for the absoulte value)

math 
drwls,
Is the 3.10 supposed to be 3 x 10, or is it just 3.10?
The beginning terms can be written
3 2^4 = 3  16
Try to do these this yourself. We will be glad to check your thinking 
math 
slimstud,
yes 3.10

math 
slimstud,
yes it's 3.10

math 
drwls,
3 2^4 + 6 8^2+3.10
= 3  16 + 6  64 + 3.10
= 13 + 9.1  64
= 13 + 54.9
Take it from there.
