We must assume that the question is asking us to determine the value of 'x'.

log(7) + log(x) = 2

log(7x) = 2

7x = 102 = 100

x = 100/7 = 14.2857 (rounded)

logx^3logx^2log14 is 3logx2logxlog14 this equals 6 log14 (logx)^2 So for example, if y=6log14(logx)^2 the log x = square root of (y/6(log14))

logx = 2 so x = 10logx = 102 = 100 ie x = 100.

Unfortunately, limitations of the browser used by Answers.com means that we cannot see most symbols. It is therefore impossible to give a proper answer to your question. Please resubmit your question spelling out the symbols as "plus", "minus", "times", "equals", "squared", "cubed" etc. Please use "brackets" (or parentheses) because it is impossible to work out whether x plus y squared is x + y^2 of (x + y)^2.

log(100x) can be written as log100 + logx. This =2+logx

2 log(4y) = log7(343) - log5(25)log7(343) = 3log5(25) = 22 log(4y) = 3 - 2 = 1log(4y) = 0.54y = sqrt(10)y = 0.25 sqrt(10)y = 0.79057 (rounded)

You use Plus as a symbol in Maths. Example, 2 Plus 2 equals 4. Or in symbols it would be 2+2=4. __________________________ Plus = + Equals = = (Equals equals =)

no if 1 plus 1 equals 2 then 2 plus 2 equals 4.

No.

2 plus 2 equals 4plus1 equals 5minus 1 equals 4divided by 2 equals 2plus 8 equals 1010 minus 6 equals 4so it all equals to +_____29so its 29 !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
