Simplify the expression.
denis23 [38]

Answer:

option d

Step-by-step explanation:

\sf \boxed{a^m*a^n = a^{m+n}\\\\}

\sf \left(\frac{m^{-1}m^{5}}{m^{-2}} \right)^{-3} =\left(\dfrac{m^{-1+5}}{m^{-2}}\right)^{-3}

                 \sf = \left(\dfrac{m^4}{m^{-2}}\right)^{-3}\\\\

\boxed{\dfrac{a^{m}}{a^{n}}=a^{m+n}}

                    \sf = \left(m^{4-[-2]}\right)^{-3}\\\\      =\left(m^{4+2}\right)^{-3}\\\\       = \left(m^6\right)^{-3}\\\\

\boxed{(a^{m})^n=a^{m*n}}

                    \sf= m^{6*(-3)}\\\\    = m^{-18}

\boxed{a^{-m}=\dfrac{1}{a^m}}

                    \sf=\dfrac{1}{m^{18}}

To plot coordinate points, look at the ordered pair (x, y).  The x value moves along the x-axis -- that is, horizontally.  If the number is positive, you move to the right, and if it's negative, to the left.  The y value moves vertically along the y-axis; if it's positive, move up, and if it's negative, move down.  Generally, we move with the x coordinate first.

Using this information,  you can either mentally plot each point or work backward to match with the letter.  Try it.
