Use exponents to write the # 81 three different ways

.

Step-by-step explanation:

We have been given  a number 81. We are asked to write 81 using exponent in three different ways.

First of all, we can write 81 raised to 1 exponent as:

.

We also know that 81 is square of 9, so we can write 81 as:

We know that 9 is square of three, so we can write 81 as:

Therefore, our required three different ways would be .

A. f(x) = (4x+5)(x-3)

              B. Since +4 > 0, the graph opens up

             as always, the vertex is at x = -b/2a = 7/8

             C. plot the vertex at (7/8, -18 1/16)

           pick a point or two, say at x=0,1,2 and plot them. then draw a curve           through them.
