Domain:\ x > 0\\\\3\ln(x)+2\ln(4)=\ln(128)\qquad\text{use}\ \lag_ab^n=n\log_ab\\\\\ln(x^3)+\ln(4^2)=\ln(128)\qquad\text{use}\ \log_ab+\ln_ac=\ln_a(bc)\\\\\ln(16x^3)=\ln(128)\iff16x^3=128\qquad\text{divide both sides by 16}\\\\x^3=8\to x=\sqrt[3]8\\\\\boxed{x=2}\in D

What is the factored form of x^12y^18+1
Black_prince [1.1K]

Answer:  The required factored form of the given expression is

(x^4y^6+1)(x^8y^{12}-x^4y^6+1).

Step-by-step explanation:  We are given to find the factored form of the following algebraic expression:

E=x^{12}y^{18}+1.

We will be using the following formula:

a^3+b^3=(a+b)(a^2+ab+b^2).

Now, we have

E\\\\=x^{12}y^{18}+1\\\\=(x^4y^6)^3+1^3\\\\=(x^4y^6+1)\{(x^4y^6)^2-x^4y^6\times1+1^2\}\\\\=(x^4y^6+1)(x^8y^{12}-x^4y^6+1).

Thus, the required factored form of the given expression is

(x^4y^6+1)(x^8y^{12}-x^4y^6+1).

Lera25 [3.4K]

Sue Brown owe $280.00 in state taxes for the month. Option B is correct.

Step-by-step explanation:

Gross pay for June= $8000

State tax rate = 3.5%

We need to find how much will Sue Brown owe in state taxes for the month.

We need to find 3.5% of 8000

Solving:

3.5\% \,\,of\,\,800\\=\frac{3.5}{100}*8000\\=280

So, Sue Brown owe $280.00 in state taxes for the month.

Option B is correct.
