Which shows how to find the value of this expression when x = negative 2 and y = 5? (3 x cubed y Superscript negative 2 Baseline

telo118 [61]

Answer:

$(3x^3y^{-2})^2$ = $\frac{576}{625}$

Step-by-step explanation:

Given:

$x=-2$

$y=5$

To evaluate:

$(3x^3y^{-2})^2$

Solution:

Applying property of exponents to simplify the expression.

Property: $(a^b)^c= a^{bc}$

So, we have: $(3x^3y^{-2})^2$

⇒ $3^2x^6y^{-4}$

⇒ $9x^6y^{-4}$

Property : $a^{-b}=\frac{1}{a^b}$

⇒ $\frac{9x^6}{y^4}$

Now, plugging in values of $x$ and $y$ .

⇒ $\frac{9(-2)^6}{5^4}$

⇒ $\frac{9\times 64}{625}$

⇒ $\frac{576}{625}$ (Answer)

A bacteria kills one third of a million ant colony daily

Valentin [98]

Answer:

Hello there!

Is your question a question cause it doesn't sound like one (I don't mean to be rude or anything)

I searched it up on the internet in a question like form

<em>(ex. What bacteria kills 1/3 of a million ant colonies daily?)</em>

and I got this.

<h2>pathogenic fungus Metarhizium</h2>

When an ant comes into contact with the pathogenic fungus Metarhizium, it has the potential to harm the entire ant colony. This is because infectious diseases can spread easily among colony members, who live closely together, and may lead to the death of the entire colony if infections are not contained.

Hope this helps!

this kills millions of ants though. (see attached image)
