Question

Pls solve this
lesson '- logarithms
(first answer will be marked as brainliest )

Answer 1

If that means log 'base 10' then, 
log (y) + 2*log (x) = 2 

{As,
a * log (x) = log (x^a)  }

So,
log (y) + log (x^2) = 2 


log (y * x^2) = 2 

We can raise 10 by both sides: 
10^(log (y * x^2)) = 10^2 
y * x^2 = 100 
y = 100 / x^2 

Hope this helps!!
cheers!! (:
