Write the expression 2i^15-i^7 in the standard form a + bi

elixir [45]

$\bf 2i^{15}-i^7\qquad 
\begin{cases}
i^2=\sqrt{-1}\cdot \sqrt{-1}\implies \sqrt{(-1)^2}\implies -1\\\\
i^4=i^2\cdot i^2\implies -1\cdot -1\implies 1
\end{cases}\\\\
-----------------------------\\\\
2i^{4+4+4+2+1}-i^{4+2+1}\implies 2i^4i^4i^4i^2i^1-i^4i^2i^1
\\\\\\
(2\cdot 1\cdot 1\cdot 1\cdot -1\cdot i)-(1\cdot -1\cdot i)\implies -2i-(-i)
\\\\\\
-2i+i\implies -i\implies \boxed{0-i}$

Write the equation of the line passing through the points (-1, 2) and (3.4)

Bond [772]

Answer:

$\boxed{y = 0,5x + 2,5}$

Step-by-step explanation:

Equation of a straight line: y = kx + b

Points: (-1,2) and (3,4)

Сompose the system of equations:

$\displaystyle \left \{ {{2=-k + b} \atop {4=3k + b}} \right$ $\displaystyle \left \{ {{b= k + 2} \atop {b=4 - 3k}} \right \Longrightarrow 2 + k = 4 - 3k$
