What would this be simplified? log9 7x + log9 x + log9 5x

OpenStudy (raden):

just multiply 7x*x*5x, what u get

OpenStudy (anonymous):

how? what would x be?

@RadEn

OpenStudy (raden):

7x*x*5x = 35x^3

OpenStudy (anonymous):

would it be log9 35x^3 or 3 log9 35x^3 ?

OpenStudy (raden):

log9 35x^3

thanks! do you know what this would be solved? 2 log2 2 + 2 log2 6 – log2 3x = 3 i know its not 2 or 6 but my calculator keeps telling me error when i plug in 16 or 18 x = 2 x = 6 x = 16 x = 18

OpenStudy (raden):

i got x=6

OpenStudy (anonymous):
