Can someone PLZZZZ HELP!!!!

Answer:

The solution is:

Part A. $\sqrt{5}^{\frac{7k}{3}})$ 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. $(x^{n})^{m} = x^{nm}$

2. $\frac{x^{n}}{x^{m}} = x^{n-m}$

3. $\sqrt[n]{x^{m}} = x^{\frac{m}{n} }$

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

$(\sqrt{5}^{3} )^{\frac{k}{9} } } = (\sqrt{5}^{3\frac{k}{9}}) = (\sqrt{5}^{\frac{k}{3}})$

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

$(\sqrt{5}^{6} )^{-\frac{k}{3} } } = (\sqrt{5}^{6\frac{k}{3}}) = (\sqrt{5}^(2k))$

Now dividing the numerator by the denominator:

$\sqrt{5}^{\frac{k}{3}-(-2k)})=\sqrt{5}^{\frac{7k}{3}})$

Part B

if $5^{\frac{3}{2} } 5^{\frac{3}{2}} = \sqrt{5}^{\frac{7k}{3}})$

Then:

$5^{3} = 5^{\frac{7k}{6}})$

So $\frac{7k}{6}} = 3$

Solving for k, we have:

k = 18/7

Answer:

$5 + 2i$

Step-by-step explanation:

We were given the complex numbers;

$a = - 2 - 5i$

and

$b = - i$

We want to find the product;

$a {b}^{3}$

We substitute the complex numbers into the expression and simplify:

$( - 2 - 5i)( {i)}^{3}$

This is rewritten as:

$( - 2 - 5i)( {i)}^{2} \times i$

Note that

${i}^{2} = - 1$

We substitute to obtain:

$( - 2 - 5i) \times - i$ Let us expand to get:

$- 2 \times - i + 5i \times - i$

This simplifies to:

$2i - 5 {i}^{2}$

This gives:

$2i - 5( - 1) = 2i + 5$

PLZZ GIVING BRAINILEST

ankoles [38]

Answer:

3.5(1.6 + 4.6 - 8.5) - 9.75
= 3.5(-2.3) - 9.75
= -8.05 - 9.75
= -17.8

Step-by-step explanation:

1.6 + 4.6 - 8.5 = -2.3
3.5(-2.3) = 3.5 × -2.3 = -8.05
-8.05 - 9.75 = -17.8

I hope this helps!
