Answer:
Annabelle is correct.
Step-by-step explanation:
1. When multiplying two numbers with exponents, the exponents are always added and not multiplied. However, when there is an number with an exponent that has an exponent (for example (5^2)^3) you would multiply them.
2. Applying this to your question would make Annabelle's work correct and Navene's work incorrect.

Answer:
I believe the answer is (A)
*Substituting the x and y values from the table into the equation(A) will balance the right side of the equation to the left side of the equation.
Answer:
25x² + 144 = (5x + 12i) (5x - 12i).
Step-by-step explanation:
We have to factorize the expression 25x² + 144, using the complex number.
Now, 
can be treated as the complex number as there is negative value with in square root.
So, 
Therefore, we can write the original expression as
25x² + 144
= 25x² - (i²)(144)
= (5x)² - (12i)²
= (5x + 12i) (5x - 12i)
So, the factorization is 25x² + 144 = (5x + 12i) (5x - 12i). (Answer)
Answer:
x=1 or x=16
Step-by-step explanation:
3/4x = 12 or 0.75x = 12
3/4x/3/4 = 12/3/4 or 0.75x/0.75 = 12/0.75
x=12/1 / 3/4
x= 4/4
x = 1 or x = 16
