Answer:Simplify (-2i)^9. (−2i)9 ( - 2 i ) 9. Apply the product rule to −2i - 2 i . (−2)9i9 ... One to any power is one. −512(1i) - 512 ( 1 i ). Multiply i i by 1 1 . −512i - 512 i.
Step-by-step explanation:
Answer:
i =−4
1=2i+9
Step 1: Flip the equation.
2i+9=1
Step 2: Subtract 9 from both sides.
2i+9−9=1−9
2i=−8
Step 3: Divide both sides by 2.
2i
=
−8
2
i=−4
