FInd all the comples sctutions of the equation. 3x^6 - 192 = 0 choose the correct solutions below 2.2i, - 1 + i Squareroot3. - Squareroot3-i, -1-1 Squareroot3, Squareroot3-i 2.1 + iSquareroot3, -1 +1iSquareroot3 -i -1-1 Squareroot3. Squareroot3 -iSquareroot3 Squareroot3 + i.21. - Squareroot3 -i, -2i, Squareroot3-i Squareroot3 + i, 1+i Squareroot3/-Squareroot3 + i, -2 2i, 1- i Squareroot3

Solution

Here we have the the rule that while subtracting two vectors, we subtract corresponding i and j terms separately.

Thus u-v = (2i-3j) -(-7i +8j)

=2i-3j +7j -8j

= (2i + 7i) + (-3j-8j)

= 9i - 11j          (as same sign numbers are always added.

So last answer is u-v = 9i - 11j

This is the answer of question 11 .
