What is the solution for (5 1/2 + 2 3/4)— 3 1/2

19/4

Step-by-step explanation:

5 1/2=11/2

2 3/4=11/4

3 1/2=7/2

11/2+11/4=22/4+11/4=33/4

33/4-7/2=33/4-14/4=19/4

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.

the correct answer to your question is a. 4^4

good luck my friend!

hope this !

maybe if i you could me by giving me brainliest?
