expand (10+6.22i)*(10+9,99i)

expand

(10 + 6.22 i) \cdot (10 + 9, 99 i)

10 \cdot 10 + 10 \cdot 9, 99 i + 10 \cdot 6.22 i + 9 \cdot 6.22 i, 99 i

Solution steps

(10 + 6.22 i) (10 + 9, 99 i)

= (10 + 6.22 i) (10 + 9 \cdot 99 i,)

Apply FOIL method:

(a + b) (c + d) = a c + a d + b c + b d

a = 10, b = 6.22 i, c = 10, d = 9, 99 i

= 10 \cdot 10 + 10 \cdot 9, 99 i + 6.22 i 10 + 6.22 i 9, 99 i

= 10 \cdot 10 + 10 \cdot 9, 99 i + 10 \cdot 6.22 i + 9 \cdot 6.22 i, 99 i

\frac{n ( n - 1 )}{2}!

\frac{1}{( s + 2 ) ^{2} ( s - 2 )}

(x + 3) (x^{2} = 7 x + 1)

(x y - 3 x - 2 y + 6) d x

(a, b, - b, a) \cdot (c, d, e, f)
