Answer:
Step-by-step explanation:
To solve this we need to take the square root of both sides with a certain degree.
We can take the root of both sides with a degree of 18.
It's helpful to understand that when a number has its square root taken with some degree n. The square root can be represented as just the value raised to the (1/n) power.
It's also helpful to understand that when you raise something to the power of another power, you can simply multiply the powers together. For instance (2^3)^5 = 2^15
Answer:
D
Step-by-step explanation:
Given
(- 4 + 5i)(5 + 2i) ← expand factors using FOIL
= - 20 - 8i + 25i + 10i² ← i² = - 1
= - 20 + 17i - 10
= - 30 + 17i
Answer:
X¹=-11; X²=3
x ^ 2 + 8x - 33 = o
x ^ 2 + 11x - 3x - 33 = 0
x(x + 11) - 3(x + 11) = 0
(x + 11)(x - 3) = 0
Answer:
x>13
