The quadratic formula works whether the coefficients of the equation are real or complex. Solve the following equations using th

RoseWind [281]

Answer:

z=i+2

,

z=i-2

Step-by-step explanation:

Remember that the quadratic equation $az^2+bz+c=0$ has the complex solutions $z=\frac{-b\pm \sqrt{b^2-4ac}}{2a}$ (this is the quadratic formula).

Apply this with a=1, b=-2i and c=-5 to get:

$z=\frac{2i\pm \sqrt{(-2i)^2-4(-5)}}{2}=\frac{2i\pm \sqrt{-4+20}}{2}=\frac{2i\pm 4}{2}$ . Then the solutions are

$z_1=\frac{2i+4}{2}=i+2$ and $z_1=\frac{2i-4}{2}=i-2$

It isn't necessary to use De Moivre's formula.

Find 4.5×10^7 over 1.5×10^-8 . write answer in scientific notation.

Sati [7]

Answer:

$\large\boxed{\dfrac{4.5\times10^7}{1.5\times10^{-8}}=3\times10^{15}}$

Step-by-step explanation:

The scientific notation:

$a\times10^k\ \text{where}\ 1\leq a$

We have:

$\dfrac{4.5\times10^7}{1.5\times10^{-8}}=\dfrac{4.5}{1.5}\times\dfrac{10^7}{10^{-8}}$

Use

$\dfrac{a^n}{a^m}=a^{n-m}$

$=3\times10^{7-(-8)}=3\times10^{7+8}=3\times10^{15}$
