Best ResponseYou've already chosen the best response.03 log 2 x + 1/2 log 2 y – 3 log 2 z = log 2 (x^3√y / z^3).

Best ResponseYou've already chosen the best response.2Okay, that's an impossible equation indeed. But it has multiple solutions.

Best ResponseYou've already chosen the best response.0So it is capable of being solved? I could call it true?

ParthKohli

Best ResponseYou've already chosen the best response.2Yes, it can be solved by using these identities:\[\log_a b + \log _a c = \log_a (bc)\]and\[\log_a b  \log_a c = \log_a (b/c)\]

Best ResponseYou've already chosen the best response.2\[\log_2x^3+\log_2y^{1/2}\log_2z^3=\log_2(x^3\sqrt{y}/z^3)\]

Best ResponseYou've already chosen the best response.2Two more:\[a\log b = \log b^a\]and\[\log_a b = \log_a c \iff b = c\]

Best ResponseYou've already chosen the best response.2I am very, very lazy and I am very, very serious about that. So I think @jiteshmeghwal9 will continue helping :p

Best ResponseYou've already chosen the best response.0It asks me if the equation is true, and if so then to explain the properties used. o.o

Best ResponseYou've already chosen the best response.2\(log_2x^3+log_2(y^{1/2})=log_2(x^3\sqrt{y})\) now \(log_2(x^3\sqrt{y})log_2z^3=log_2(x^3\sqrt{y}/z^3)\)

Best ResponseYou've already chosen the best response.2That's it, right there. ^

Best ResponseYou've already chosen the best response.2\[\log_2x^3+\log_2y^{1/2}\log_2z^3=\log_2(x^3\sqrt{y}/z^3)\]since\[\log_2x^3+\log_2(y^{1/2})=\log_2(x^3\sqrt{y})\]\[\log_2(x^3\sqrt{y})\log_2z^3=\log_2(x^3\sqrt{y}/z^3)\]so,\[\log_2(x^3\sqrt{y}/z^3)=\log_2(x^3\sqrt{y}/z^3)\]H.P.

Best ResponseYou've already chosen the best response.0I am so confused. Thank you everyone for the help, I'll just do my best to take the identities you both listed and write something about it. Very much appreciated!

Best ResponseYou've already chosen the best response.0By properties they mean the logarithmic properties :c I just asked my teacher. So the power property, the product property, and the quotient property? Would any of those fit?

Best ResponseYou've already chosen the best response.0Power Property \[\log a^b=b \log a\] Product Property \[\log ab= \log a +\log b \] Quotient property \[\log \dfrac{a}{b}=\log a  \log b\]

Best ResponseYou've already chosen the best response.2\(blog_ac=log_ac^b\) \(log_ab+log_ac=log_abc\) \(log_ab  log_ac=log_a\dfrac{b}{c}\)

Best ResponseYou've already chosen the best response.2these are the only properties used in the question

Best ResponseYou've already chosen the best response.0How do they show that the equation is true, though?
