Answer:

Step-by-step explanation:
We want to write the conjugate of the complex number:

Recall that the conjugate of a complex number in the form <em>a</em> + <em>b</em>i is <em>a</em> - <em>b</em>i, and vice versa.
We can rewrite our complex number as:

Hence, <em>a</em> = 0 and <em>b</em> = 6.
Then its conjugate will be:

Use BODMAS, this is the order in which you must
1. Brackets
2. Divide
3. Multiply
4. Add
5. Subtract
therefore 2x2+2x2-2+2x2=10
Answer:
2(4a + 7)
Step-by-step explanation:
2 to the 4 and 7
This would give you 8a + 14 because 2 times 4 is 8, and 2 times 7 is 14.
