Which expression is equivalent to 1/√121x^9y^8z^10
sweet [91]

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
