Me simplify this fraction. or is it already in its simplest form?

1 / x^8

Step-by-step explanation:

We know that a^b / a^c = a^ (b-c)

x^7 / x^ 15 = x^ (7-15) = x^-8

We also that that a^-b = 1/ a^b

x^-8 = 1 / x^8

1/(x^8)

Step-by-step explanation:

Simplify by the following steps. To make it easier, I will expand them:

First, expand each of the powers out:

When dividing with the same variables with different powers, you are effectively subtracting the powers. Your answer will look like:

Next, simplify. Note that if there is a negative sign in the power, you must change the sign into a positive by flipping the fraction.

1/(x^8) is your answer.

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.

answer: 8d

step-by-step explanation:

45+5= 50+5=55+5=60
