You cannot solve log x- 2 unless (i) log x - 2 is equal to some number or (ii) x is equal to some number.

How do you solve log x plus 2 equals log 9?

log x + 2 = log 9 log x - log 9 = -2 log (x/9) = -2 x/9 = 10^(-2) x/9 = 1/10^2 x/9 = 1/100 x= 9/100 x=.09

How do you solve log base 2 of x - 3 log base 2 of 5 equals 2 log base 2 of 10?

[log2 (x - 3)](log2 5) = 2log2 10 log2 (x - 3) = 2log2 10/log2 5 log2 (x - 3) = 2(log 10/log 2)/(log5/log 2) log2 (x - 3) = 2(log 10/log 5) log2 (x - 3) = 2(1/log 5) log2 (x - 3) = 2/log 5 x - 3 = 22/log x = 3 + 22/log 5


How do you solve 2logx plus 3logx equals 10?

2 log(x) + 3 log(x) = 105 log(x) = 10log(x) = 10/5 = 210log(x) = (10)2x = 100


How do you solve 2 raised to the x equals 3?

To solve the equation (2^x = 3), take the logarithm of both sides. This can be done using either natural logarithm (ln) or common logarithm (log): [ x = \log_2(3) = \frac{\log(3)}{\log(2)} ] This gives you the value of (x) in terms of logarithms. You can then use a calculator to find the numerical value if needed.


How do you solve 3 log of 8 equals x?

x = 3*log8 = log(83) = log(512) = 2.7093 (approx)


How do you solve 3 to the power of negative 2x plus 2 equals 81?

3^(-2x + 2) = 81? log(3^(-2x + 2)) = log(81) (-2x+2)log(3) = log(81) -2x = log(81)/log(3) - 2 x = (-1/2)(log(81)/log(3)) + 1


Log x plus log 2 equals log 2?

log(x) + log(2) = log(2)Subtract log(2) from each side:log(x) = 0x = 100 = 1

How do you solve Log3 log2x - log(3x plus 7)?

To solve the equation ( \log_3(\log_2 x) - \log(3x + 7) = 0 ), first rewrite it as ( \log_3(\log_2 x) = \log(3x + 7) ). This implies ( \log_2 x = 3^{\log(3x + 7)} ). Next, convert ( \log(3x + 7) ) to base 3, and isolate ( x ) by converting back to exponential form. Finally, solve the resulting equation for ( x ).


Why is the answer for log x squared equals 2 different than 2log x equals 2?

log x2 = 2 is the same as 2 log x = 2 (from the properties of logarithms), and this is true for x = 10, because log x2 = 2 2 log x = 2 log x = 1 log10 x = 1 x = 101 x = 10 (check)
