Answer:
For addition and subtraction, use the standard + and - symbols respectively. For multiplication, use the * symbol. A * symbol is not necessary when multiplying a number by a variable. For instance: 2 * x can also be entered as 2x. Similarly, 2 * (x + 5) can also be entered as 2(x + 5); 2x * (5) can be entered as 2x(5). The * is also optional when multiplying with parentheses, example: (x + 1)(x - 1).
Step-by-step explanation:
Its right?
Answer:
The solution is:
Part A.
which is sqrt(5)^7k/3[/tex]
Part B. k = 18/7
Step-by-step explanation:
Part A.
To solve this part, we're going two use THREE important properties of exponents:
1. 
2. 
3. ![\sqrt[n]{x^{m}} = x^{\frac{m}{n} }](https://tex.z-dn.net/?f=%5Csqrt%5Bn%5D%7Bx%5E%7Bm%7D%7D%20%3D%20x%5E%7B%5Cfrac%7Bm%7D%7Bn%7D%20%7D)
Let's work the numerator using the properties 1, 2 and 3:

Let's work the denominator using the properties 1, 2 and 3:

Now dividing the numerator by the denominator:

Part B
if 
Then:

So 
Solving for k, we have:
k = 18/7
