81 is the same as 3⁴.

Thus, we can write it as:
(3x)^{4} - 3^{4}
= [(3x)^{2}]^{2} - [3^{2}]^{2}
= [(3x)^{2} - 3^{2}][(3x)^{2} + 3^{2}]
= (3x - 3)(3x + 3)[(3x)^{2} + 3^{2}]
= (3x - 3)(3x + 3)(9x^{2} + 9)

Plz help with this problem!<br><br> x^4 + x^2 + 1
TEA [102]

Answer:

You cannot simplify this problem down anymore; it is at its simplest form.

Step-by-step explanation:

You cannot add together x^4 and x^2 due to the simple fact that they do not share similar exponents.

For example you could add together x^4 and x^4 to get 2x^4. But you cannot add x^4 and x^2.

One survey estimates that,on average, the retail value of a mid sized car decreases by8% annually.if the retail value of a car i
Scrat [10]
Percentage by which the average value of mid sized car decreases each year = 8%
Retail value of a car today = v dollars
Amount of decrease in the value of the car after 1 year = (8/100) * v
                                                                                         = 2v/25 dollars
Then
The equation that represents the value of the car after 1 year = v - (2v/25) dollars
                                                                                                   = (25v - 2v)/25 dollars
                                                                                                   = 23v/25 dollars
So following this expression the value of the mid sized car can be easily determined after 1 year. I hope this is the answer you were looking for and the procedure is also clear to you.
