The logarithm function is defined so that if
y = 10x then log y = x
So, if x = 1, y = 101 = 10
and so log 10 = 1

How do you solve log basex 3 equals log7?
logx(3) = log10(7) (assumed the common logarithm (base 10) for "log7") x^(logx(3)) = x^(log10(7)) 3 = x^(log10(7)) log10(3) = log10(x^(log10(7))) log10(3) = log10(7)log10(x) (log10(3)/log10(7)) = log10(x) 10^(log10(3)/log10(7)) = x
Log 225 to the 2 power equals 3.456?
log10(225)2 equals 5.5327625985087111
What is the pH for a solution that has h plus equals 3.6 x 10 -9 M?
pH means -log10(H+concentration) so pH of a H+ concentration 3.6x10-9 is: pH = -log10(3.6x10-9) ≈ 8.4
To count the no of digits in an integer?
Say you have some integer a. aFirst take it's absolute value. |a|Next log it base 10. log10 |a|Truncate this value, then add 1. trunc ( log10 |a| ) + 1You now have the number of digits.
What is difference between natural logarithm and log base 10?
The natural logarithm is calculated to base e, where e is Euler's constant. For any number, x loge(x) = log10(x)/log10(e)

What is the pH of a solution that results from mixing 15.265 g of benzoic acid C6H5COOH MM equals 122.1 and 12.97g of sodium benzoate NaC6H5COO MM equals 144.1 in water to produce 500 ml of solution?
To calculate the pH of the solution, you need to consider the dissociation of benzoic acid and sodium benzoate. Since benzoic acid is a weak acid, it will partially dissociate, while sodium benzoate will fully dissociate into its ions. Together, they will create a buffer solution. You will need to calculate the concentrations of the acid and conjugate base, use the Henderson-Hasselbalch equation, and consider the ionization constant of benzoic acid to determine the pH.

What is the pH of a solution with h plus equals 7.0 x 10-2?
The pH of a solution with [H+] = 7.0 x 10^-2 M is pH = -log(7.0 x 10^-2) = 1.15.
What to what power equals 99?
There is no simple answer. 10 to the power 1.995635 (approx) = 99 The number 1.995635 is log10(99)
What is the pH for a solution that has h plus equals 3.6 x 10 -9 M?
pH means -log10(H+concentration) so pH of a H+ concentration 3.6x10-9 is: pH = -log10(3.6x10-9) ≈ 8.4
What is the pH of an aqueous solution if the concentration of H plus equals 0.00097?
pH s calculated as the negative log10 of the hydrogen ion concentration. So log10 of 0.000724 = -3.14 so pH= 3.14
Why log 0 equals infinity?
log10 0 is actually undefined. Think about it like this: If loba b = y then we know that ay = b This means that log10 0 = y translates to 10y = 0 But as you know, 10y is always greater than zero. Therefore 10y = 0 is undefined. Therefore log10 0 = y is undefined.

How do you solve for pH?
Let us assume you have a Hydrochloric acid solution of 0.1 M. The pH is - log10[H+]. So log10[0.1] = -1 easy way to remember this is 103 =1000 log 101000 = 3 102 =100 log 10100 = 2 101 =10 log 1010 = 1 100 =1 log 101 = 0 10-1 =0.1 log 100.1 = -1 10-2 =0.01 log 100.01 = -2 So log10[0.1] = -1 and thus pH is - log10[H] = (minus minus 1) = 1
Why does pi log 10 equal pi?
xlog10 = x This is a simple rule of logs, because log(base10)10 = 1. Any value multiplied by one equals itself. So pi*log10 = pi(1) = pi.
