Log5 2 plus log5 10 - log5 4?
log5(2) + log5(10) - log5(4) = log5(20/4) = log5(5) = 1
How do you solve log5 20 plus log5 10 - 3log5 2?
log5 20 + log5 10 - 3log5 2 = log5 [(20*10)/(2^3)] = log5 25 = 2 (log5 5) = 2
When you calculate log5 you would be finding the value of what expression?
The base of log, if unspecified, is taken to be 10 so you would be finding the value of the logarithm of 5 to the base 10.This is the value x, such that 10^x = 5.
2log 4y equals log 7 343 - log 5 25?
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)
How do you find the inverse log using a TI 84 plus?
The 2nd function of the log button is the inverse log. Press 2nd log, which displays 10^( on the screen. Put a number after the opening parenthesis.
Condense this logarithim log5 plus log2?
log5 +log2 =log(5x2)=log(10)=log10(10)=1
Log5 2 plus log5 10 - log5 4?
log5(2) + log5(10) - log5(4) = log5(20/4) = log5(5) = 1
How do you solve log5 20 plus log5 10 - 3log5 2?
log5 20 + log5 10 - 3log5 2 = log5 [(20*10)/(2^3)] = log5 25 = 2 (log5 5) = 2
When you calculate log5 you would be finding the value of what expression?
The base of log, if unspecified, is taken to be 10 so you would be finding the value of the logarithm of 5 to the base 10.This is the value x, such that 10^x = 5.
What is the answer for 2 log x - log 5 equals -2?
2logx-log5=-2 logx^2-log5=-2 log(x^2 / 5)=-2 x^2 / 5 = 10^-2 x^2=5(1/100) x^2=1/20 x=√(1/20)
2log 4y equals log 7 343 - log 5 25?
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)
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
What is the numeric value of log?
The numeric value of log(x) is the power you have to raise 10 to in order to get 'x'.
What is value of log?
log (short for logarithm) does not actually have a value. It is actually an operation. So if you see log(10), for instance, you need to take the logarithm of the number in the parenthesis. To do that, just ask yourself "ten raised to WHAT POWER equals the number inside the parenthesis?" And log(#) = that exponent. To finish the example above, log(10) asks you 10? = 10. The answer here is 1, so log(10)=1.
What is the pH of a solution with a H plus equals 10 -8?
2
What is the pH of a solution with H plus 2.3x 10-9?
Since the pH is defined as the negative log of the H+ concentration, one simply needs to take the negative log of 2.3x10^-9. This value = pH = 8.6
Log9x plus log x equals 4log10?
log(9x) + log(x) = 4log(10)log(9) + log(x) + log(x) = 4log(10)2log(x) = 4log(10) - log(9)log(x2) = log(104) - log(9)log(x2) = log(104/9)x2 = 104/9x = 102/3x = 33 and 1/3
