Simplify the expression using properties of exponents. 25a^-5b^-8/5a^4b

Mathematics
1 answer:
ivanzaharov [21]3 years ago
6 0

Answer: The simplification is 5*a^{-9}*b^{-9}

Step-by-step explanation:

Here we need to use the property:

\frac{a^n}{a^m} = a^{n - m}

We have the expression:

\frac{25*a^{-5}*b^{-8}}{5*a^{4}*b}

We can separate it in parts with the same base, then we can rewrite this as:

\frac{25*a^{-5}*b^{-8}}{5*a^{4}*b} = \frac{25}{5} \frac{a^{-5}}{a^4} \frac{b^{-8}}{b}

Using the first property we can rewrite this as:

\frac{25}{5} \frac{a^{-5}}{a^4} \frac{b^{-8}}{b} = 5*a^{-5 - 4}*b^{-8 - 1} = 5*a^{-9}*b^{-9}

Find the midpoint of the line segment with end coordinates of:
Arisa [49]

Answer:

The midpoint of this line segment is (-1.5, -4.5).

Step-by-step explanation:

In finding the midpoint of a line segment we are actually averaging the x- and y-coordinates of the endpoints:

                                             -2 -1

x-coordinate of midpoint = --------- = -3/2 = -1.5

                                                 2

                                              -4 -5

y-coordinate of midpoint = ---------- = -4.5

                                                   2

The midpoint of this line segment is (-1.5, -4.5).
