What is x plus x plus 2 x equal 3?
log33+log3x +2=3 log33+log3x=1 log3(3x)=1 3x=3 x=1 Other interpretation: log33+log3(x+2)=3 log3(3(x+2))=3 3(x+2)=27 x+2=9 x=7
What is the pH of a soultion that has a h plus concentration of 0.001m?
pH = -log10[H+] = -log10(0.001 mol/L )= -log10(10-3)= 3
What is Log3 3 plus log3 x plus 2 equals 3?
log33+log3x +2=3 log33+log3x=1 log3(3x)=1 3x=3 x=1 Other interpretation: log33+log3(x+2)=3 log3(3(x+2))=3 3(x+2)=27 x+2=9 x=7
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
What is the pH of a solution with H plus 7.0 x 10-2?
The little 'p' means -log10 (that's the negative log to base 10). Thus pH means -log10(Hydrogen ion concentration) → pH of the solution = -log10(7.0 x 10-2) ≈ 1.15
What is The log10 of 0.00000001 is?
The logarithm base 10 (log10) of 0.00000001 can be calculated as follows: 0.00000001 is equivalent to 10^-8. Therefore, log10(0.00000001) = log10(10^-8) = -8.
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
Condense this logarithim log5 plus log2?
log5 +log2 =log(5x2)=log(10)=log10(10)=1

How natural log can be converted into common logaritms?
ln(x) = log10(X)/log10(e)
What is log10 100?
10 log10 (100) or 10 (the exponent of 10 that gives you 100) 10 (2) 20
What is 7 to the power of 2011 equal to?
That goes beyond the capabilities of most scientific calculators, but you can calculate it with logarithms:x = 7^2011 log10(x) = log10(7^2011) log10(x) = 2011 log10(7) x = 10^(2011 log10 7) x = 10^1.699,49 x = 10^0.49 times 10^1699 x = 3.09 times 10^1699
