14. if s and t are normal linear operators satisfying st*-ts and ts*=s*t, show that their sum s+t and product st are normal. 15. show that a bounded linear operator t: hh on a complex hilbert space h is normal if and only if llt*xll-itxll for all xe h. using this, show that for a normal linear operator,

answer: 25 is the correct answer

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|
