Answer:
Z=+6
Step-by-step explanation:
Z^5=-7776i
Let's note that i I mathematics means negative one i.e
i = -1
So the equation is equal to
Z^5=-*-(7776)
Z^5 = 7776
Z= 5√7776
Since it's a divisible by 6
It's giving us a clue that 6 it's the answer.
Ok let's check the 5th root of 7776 in our calculator.
Z=+6
+6 is the solution to the equation
Z^5=-7776i
I think is the answer because the right side =0 and so basically your left with the left side. 6(x² - 1)
Answer:
<h3>-8 divided by (-4)</h3>
Step-by-step explanation:
-18 divided by -9 is <u>+2</u> and that is what you want.
-18 divided by 2 is -9, not correct.
-12 divided by (-3) is +4, not correct.
-10 divided by 5 is -2, not correct.
Leaving the <em>correct</em> answer: -8 divided by (-4) is <u>+2</u>.
Remember: a negative times a negative equals a positive.
The first one will flash at every 30 sec and the second one at 20 sec. The second one will go like 1- 4- 8 and then to 12. By the time the second one will reach first at 6 and then on 12. So, after every 1 minute they will flash together.
