Answer:
±6i√2
Step-by-step explanation:
Recall that the square root of a negative number is imaginary, which is shown by the use of "i."
Examples: √4 = ±2; √4 = i√4 = ±i2
Then √72 = ±√36√2 = ±6√2, and
√(-72) = ± i√36√2 = ±6i√2
Note that this is identical to the result shown in the problem: √(36·2·(-1) )
Answer:
28th
Step-by-step explanation:
Put that value into the formula and solve for n.
191 = 2 +7(n -1)
(191 -2)/7 = n-1 . . . . . . . subtract 2 and divide by 7
27 +1 = n . . . . . . . . . . . .add 1
191 is the 28th term in the sequence.
