Which is the greatest common factor of the expression below?<br> 32a²b2 + 36a²c2 – 16ab3
yKpoI14uk [10]

Answer:

Step-by-step explanation:

32a²b²  = 2 * 2*2*2*2 * a² * b²

36a²c² = 2 * 2 * 3 * 3 * a² * c²

16ab³  = 2 * 2 * 2* 2 * a * b³

Greatest common factor =  2*2*a = 4a

32a²b² + 36a²c² - 16ab³ = 4a*(8ab² + 9ac² - 4b³)

Help please thank you

One of the rules of logarithms is as follows;

\begin{gathered} \log _ab=x \\ Is\text{ equivalent to,} \\ a^x=b \end{gathered}

We can now insert the corresponding values in the question provided, as shown below;

\begin{gathered} \log _2\frac{1}{16}=-4 \\ \text{This is equivalent to,} \\ 2^{-4}=\frac{1}{16} \end{gathered}

Note that, one of the rules of exponents, states that a number when raised to the power of a negative value, is equivalent to the reciprocal of that expression. An example is shown below;

a^{-x}=\frac{1}{a^x}

Therefore, our equation can now be re-written as follows;

\begin{gathered} 2^{-4}=\frac{1}{16} \\ \frac{1}{2^4}=\frac{1}{16}^{} \\ \frac{1}{16}=\frac{1}{16} \end{gathered}

However, the question requires the answer to be expressed in exponential form. Therefore,

\log _2\frac{1}{16}=2^{-4}

What are the values of a and b in the equation a[3x-8]=b-18x
3241004551 [841]
A(3x-8)=0

a=0 and x=8/3

This second line is not necessarily true. We could have a=0 OR x=8/3. They don't both have to be 0. a(3x-8)=b-18x

No solutions found

Rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

a*(3*x-8)-(b-18*x)=0

Step by step solution :

Step 1 :

Equation at the end of step 1 :

a • (3x - 8) - (b - 18x) = 0
Step 2 :

Equation at the end of step 2 :

3ax - 8a + 18x - b = 0
Step 3 :

Solving a Single Variable Equation :

3.1 Solve 3ax-8a+18x-b = 0
