Prime factorization, Exponents

Click For Summary
The problem involves finding z in the equation xx*yy=zz, where x and y are products of prime factors. The values for x and y are given as x=28 * 38 and y=212 * 36. The solution reveals that zz can be expressed in terms of prime factorization, leading to z being calculated as z = {2^{11}*3^{7}}. The discussion emphasizes the importance of understanding prime factorization and exponents to solve such problems effectively. Ultimately, the key takeaway is that z can be derived from the prime factorization of the products involved.

Homework Statement


xx*yy=zz

find z if:
x=28 * 38
y=212 * 36

Homework Equations


there's undoubtably some trick, but I have yet to find it

The Attempt at a Solution


Dont even think about calculator

I showed my math teacher, and he was able to find that zz=2(211*37*11) * 3(211*37*7)

or 249268736 * 331352832

How do you get z alone?
 
Physics news on Phys.org
z^{z} = 2^{2^{11}*3^{7}*11} * 3^{2^{11}*3^{7}*7} = ({2^{11}})^{2^{11}*3^{7}}*({3^{7}})^{2^{11}*3^{7}} = ({2^{11}*3^{7}})^{2^{11}*3^{7}}

z = {2^{11}*3^{7}}
