Answer:

The answer is B) 1/25

Step-by-step explanation:

This is because given that f(x) = 5^x

Hence, f(-2) would be 5^-2, which is equal to (1/5^2) => 1/25

Because a^-b can be written as 1/a^b

Which product of prime polynomials is equivalent to 3x4 – 81x?
adelina 88 [10]

Given:

The expression is

3x^4-81x

To find:

The product of prime polynomials which is equivalent to the given expression.

Solution:

We have,

3x^4-81x

Taking out the common factors, we get

=3x(x^3-27)

It can be written as

=3x(x^3-3^3)

=3x(x-3)(x^2+3x+3^2)        [\because a^3-b^3=(a-b)(a^2+ab+b^2)]

=3x(x-3)(x^2+3x+3^2)

=3x(x-3)(x^2+3x+9)

Therefore, the correct option is B.

To solve/simplify this all you have to do is group like terms (the x^2's with each other, the x's with each other, and the normal numbers, -8)

14x^2-8+5x-6x^2+2x

group the x^2 (add 14x^2 to -6x^2)

8x^2-8+5x+2x

group the x's together (add 5x and 2x together)

8x^2+7x-8

Your answer will be d) 8x^2+7x-8
