Answer
7
Step-by-step explanation:
Here are some examples:
Square root: √x = x^(1/2)
Cube root: ∛x = x^(1/3)
nth root: x^(1/n)
... and so on.
Answer:
x = 5
Step-by-step explanation:
The opposite sides of a parallelogram must be parallel to each other, and this is shown by the equivalent opposite interior angles on each side of the bisector.
Since the opposite sides of a parallelogram are parallel, they must be of equal length (this is one of the fundamental properties of a parallelogram).
Therefore, we can set (18x - 5) and (16x + 5) equal to each other in an equation and solve for x.
Subtract 16x from both sides.
Add 5 to both sides.
Divide both sides by 2.
The value of 5 for x must make ABCD a parallelogram.
Answer:
= 16+49 = 65
Step-by-step explanation:
The error is at the end of the first line. (-7i)(7i) = -49i² ≠ +49i².
The correct work is ...
(4-7i)(4+7i)=16+28i-28i-49i^2
= 16+49
= 65
