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)

LenKa [72]

Answer:

$7.7 million

Step-by-step explanation:

Given: $6.8 million profit made by company.

           13% increase in profit every year.

Now, finding the company´s profit in the year of 2006.

As we know there is 13% increase in profit.

∴ Profit increase= \frac{13}{100} \times 6.8= \$ 0.884

Next adding company´s profit with increase in profit to get profit in the year 2006.

∴ 6.8+0.884= \$ 7.684 ≅ $7.7

The company´s profit in the year 2006 is $7.7 million.
