20 points + brainliest = 30 points!
riadik2000 [5.3K]

Answer:

see below

Step-by-step explanation:

Addition and subtraction are both closed under polynomials.

That means that when we add and subtract polynomials, we will end up with a polynomial

f(x) + g(x) will =  always be a polynomial when we start with polynomials

f(x) - g(x) will =  always be a polynomial when we start with polynomials

Tori examined the pattern of exponents in the table.
gregori [183]

Answer:

The value of b = 1/36

As exponent decreases, each previous value is divided by 6

If the table was extended, the value of 6^-3 would be 1/216

Step-by-step explanation:

Given in the question a table containing power of 6

We will use negative rule of exponent to write the equivalent of negative power of 6

b^{-n}= 1 / b^{n}

we know that

6^{1}=6

so

6^{-1} =\frac{1}{6^{1} }

= 1/6

and

6^{2} = 36

So,

6^{-2} = \frac{1}{6^{2} }

=

\frac{1}{36}
