Answer:

p=-9

Step-by-step explanation:

We want to solve the linear equation;

7p=-63

We divide both sides of the given linear equation by 7 to obtain;

\frac{7p}{7}=\frac{-63}{7}

This implies that;

p=\frac{-63}{7}

p=\frac{-9\times7}{7}

We now cancel out the common factors to get:

p=-9

Please find the square roots of the following complex number.
Nana76 [90]

Hey there,

First, find the square root of the given equation.

\sqrt{z}=\sqrt{81(\text{cos}(\frac{4\pi}{9})+i\text{sin}(\frac{4\pi}{9})}\\=9\text{cos}\frac{1}{2}(2k\pi+(\frac{4\pi}{9}))+i\text{sin}\frac{1}{2} (2k\pi+(\frac{4\pi}{9}))

Keep in mind that this is solved for k = 0 and 1.

Second, simplify.

=9\text{cos}(\frac{2\pi}{9})+i\text{sin}(\frac{2\pi}{9})~\text{or}~9\text{cos}(\frac{11\pi}{9})+i\text{sin}(\frac{11\pi}{9})

Best of Luck!
