answer:
4 square root of 2 i (i it's outside the square root)
explanation:
square root of -2 = square root of 2 i (i being outside)
and square root of -18 = square root of 1 and square root of 9*2, square root of 1 = i, and the square root of 9 is 3, leaving square 2 alone
so it would look like:
square root of 2 i PLUS 3 square root of 2 i (i being outside as well)
there is a 1 outside the square root of 2 i, that 1 adds up with the 3 and since the square roots are the same, they stay the same
so 4 square root of 2 i
Given:
Resistance
Inductive reactance
We can calculate total impedance (Z) in parallel circuit, by using a reciprocal formula (identical to that used in calculating parallel resistances in DC circuits) as follows.
solving this we get, Z = 18.4798 kΩ
The value of the expression (e+c-d)x dn is -2
The given expression is:
(e+c-d)x dn
Substitute e=-6, n=2, c=6, and d=-1 into (e + c - d) x dn
(e+c-d)x dn = [-6 + 6 -(-1)] x (-1)(2)
(e+c-d)x dn = (0 + 1) x (-2)
(e+c-d)x dn = 1 x (-2)
(e+c-d)x dn = -2
