A perpendicular bisector forms two right angles and splits the line in two equal parts.

The altitude does create two right angles, but doesn't have to create two equal parts.

30 POINTS!!!!!!!!!!!!!!!!!!!!!! 4 x times the fraction 1 over x to the power of negative 5 times x to the power of negative 3

DaniilM [7]

Answer:

$4 {x}^{3}$

Step-by-step explanation:

We want to simplify

$4x \times ( \frac{1}{x})^{ - 5} \times {x}^{ - 3}$

Recall the reciprocal property:

$\frac{1}{a} = {a}^{ - 1}$

We apply this property to get:

$4x \times ( {x}^{ - 1} )^{ - 5} \times {x}^{ - 3}$

Also apply this property of exponents to get:

${(a}^{m})^{n} = {a}^{mn}$

$4x \times ( x )^{ 5} \times {x}^{ - 3}$

We simplify using the product property of exponents to get:

$4 {x}^{1 + 5 - 3} = 4 {x}^{3}$
