What is the common logarithm of 0.072?
The common logarithm of a number is the exponent to which 10 must be raised to equal that number. In this case, the common logarithm of 0.072 is -1.1438. This is because 10 raised to the power of -1.1438 is approximately equal to 0.072.
What is pH equals -log10 H plus?
Definition to use for the log (logarithm):the logarithm of a number (n) to a given base (b) is the exponent (e) to which the base must be raised in order to produce that number.(Raising to the power is the inverse of taking the logarithm.)logb(n) = e or be = nFor example, the logarithm of 1000 to base 10 is 3 ( log10(1000) = 3),because 10 to the power of 3 is 1000: 103 = 1000.-log10[H+] is (by definition) used to calculate the pH of a dilute solution in which [H+] = concentration of H+ (or H3O+) in mol/L.pH = -log10[H+] or [H+] = 10-pH
Which expression is equevilent to 15x plus 3?
15xplus 3
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
What is x plus 3 plus 2x cubed?
It is an expression which can be written in the form of: 2x3+x+3
