we have the number

6-\sqrt[]{-40}

Remember that

i^2=-1

so

substitute

6-\sqrt[]{(i^2)40}6-2i\sqrt[]{10}

therefore

the real part is 6

the imaginary part is -2√10

telo118 [61]
Using the method of checking each answer to see if it is possible that they are correct. 

The 3 in the 350 can also be referred to as just 300 because it a 3 in the hundreds place. Also because if the rest of the numbers following the "3" were zeros the number would be 300.
The 3 in the 403 can be just referred to as 3 because there are no other numbers following it, and the 3 is in the ones place. 

A. THE 3 IN 350 IS 10 TIMES THE VALUE OF THE 3 IN 403
-Saying that 300 is ten times greater than 3-
To check that would mean that:
300 = 3x10
300=30
300≠30
ANSWER A DOES NOT WORK BECAUSE 300 DOES NOT EQUAL 30

B: THE 3 IN 350 IS 100 TIMES THE VALUE OF THE<span> 3</span><span> IN 403
</span>-Saying that 300 is one hundred times greater than the 3-
To check that would mean that:
300=3(100)
300=300
ANSWER B WORKS AND IS THE CORRECT ANSWER BECAUSE 300=300

C: THE 3 IN 403 IS 10 TIMES THE VALUE OF THE 3 IN 350
-Saying that the 3 in ten times greater than the value of 300-
To check that would mean that:
3=300x10
3=3000
3≠3000
ANSWER C DOES NOT WORK BECAUSE 3 IS NOT EQUAL TO 3000

<span>D: THE 3 IN 403 IS 100 TIMES THE VALUE OF THE 3 IN 350
-Saying that 3 is one hundred times greater than 300-
To check that would mean that:
3=300(100)
3=30000
3</span>≠30000
ANSWER D DOES NOT WORK BECAUSE 3 IS NOT EQUAL TO 30000

THE CORRECT ANSWER IS B
