Answer:
64
Step-by-step explanation:
first, we'll start with the value inside the parenthesis, which is 2³
2³ means to multiply 2 by itself 3 times
so it would be
2×2×2=8
which then means that the expression is now (8)²
now we need to do (8)², which is to multiply 8 by itself twice
8*8=64
hope this helps!
Answer:
80 + 18i
Step-by-step explanation:
i² = -1
x = i + 9
x² = (i + 9)²
Applying; (a + b)² = a² + 2ab + b² concept,
x² = i² + 18i + 81
We know that i² = -1
So x² = -1 + 18i + 81
x² = 81 - 1 + 18i = 80 + 18i
