----
x = 5000^(1/12) = 2.0335
y = x^11/10 = 2.0335^11/10 = 245.88
-------------------------
Ans: xy = 2.0335*245.88 = 500

It would've been nice if it were stated that this should be done WITHOUT a calculator

x%5E12+=+%225%2C000%22

matrix%281%2C3%2C+x%5E11%2Fy+=+10%2C+%22======%3E%22%2C+x%5E11+=+10y%29 ------- Cross-multiplying
