Evaluate. Write in standard form.
Feliz [49]

Answer:

-i

Step-by-step explanation:

(-i)^0 = 1

(-i)^1 = -i

(-i)^2 = -1

(-i)^3 = -i

(-i)^4 = 1

(-i)^5 = -i

etc.

From this pattern, you see that when the exponent is a multiple of 4, you get 1. When the exponent is a multiple of 4 plus 1, you get -i, etc.

213 = 4 * 53 + 1

213 is 1 more than a multiple of 4.

(-i)^213 = (-i)^1 = -i

2/3(9a+18b)=6a+kb
bagirrra123 [75]

Answer:

4.) 12

Step-by-step explanation:

\frac{2}{3} (9a + 18b) = 6a + kb \\  \\  \implies \:  \frac{2}{3}  \times 9a +  \frac{2}{3}  \times 18b = 6a + kb \\  \\  \implies \: { 6a} + 12b = 6a + kb \\  \\  \implies \:  \cancel{ 6a} + 12b -  \cancel{ 6a} = kb \\  \\  \implies \:  12b = kb \\  \\ \implies \: k =  \frac{12\cancel b}{\cancel b}  \\  \\ \huge \implies \: k = 12
