Answer:

1/(11 x^(9/2) y^4 z^5)

or

sqrt(x)/ 11 x^5 y^4 z^5  

Step-by-step explanation:

1/ sqrt(121x^9y^8z^10)


Lets simplify the denominator

sqrt(121x^9y^8z^10)

Break it into pieces

sqrt(121) sqrt(x^9) sqrt(y^8) sqrt(z^10)

11  sqrt (x^8) sqrt(x) y^4  z^5

11 x^4 y^4 z^5  * sqrt(x)  



Putting this back in

1

----------------------------

11 x^4 y^4 z^5  * sqrt(x)


But we dont want a sqrt root in the denominator

Multiply by sqrt(x)/sqrt(x)

sqrt(x)

----------------------------

11 x^4 y^4 z^5  * sqrt(x) sqrt(x)

sqrt(x)

----------------------------

11 x^4 y^4 z^5  * x

sqrt(x)

----------------------------

11 x^5 y^4 z^5

An element with mass 780 grams decays by 17.1% per minute. How much of the element is remaining after 19 minutes, to the nearest
VikaD [51]

Answer:

  22.1 grams

Step-by-step explanation:

At the end of each minute, (1 -17.1%) = 82.9% of the element remains. At the end of 19 minutes, the quantity has been multiplied by that value 19 times, so the remaining amount is ...

   (780 g)(0.829^19) ≈ 22.1 g

After 19 minutes 22.1 grams remain.
