Explain the difference between log base b (mn) and ( log base b of m)(log base b of n). Is the following below correct? Log ar^2 - Log ar= Log ar - Log a hence applying laws of logarithm Log(ar^2/ar) = log(ar/a) Log and log cancels out and then cross-multiply hence a^2r^2 = a^2r^2 L.H.S=R.H.S Prove that log a, log ar, log ar^2 is an a.p. 1/2 log base b of (x-2)- log base b of y + (3 log base b of z) = log base 6 of (x-2)^1/2 Mathematically Evaluate without using tables 2 log base 10 raised 2 power 5 + log base 10 36 - log base10 9 that is, 2log10 5 +log 10 36 - log 10 9
DERIVATIVE OF LOG BASE 8 HOW TO
log base 10 (9/300) log - log 300 log 9 = 2 log 3 log 300 = log 3 + log 100 = log 3+2 I just do not know how to put these together now!
pH=4.7 pKa of acetic acid=4.76 Not sure if I did this next part right: 4.7=4.76 + log / -0.06= logġ) use the properties of logarithms to simplify the logarithmic expression. Available is sodium acetate and glacial acetic acid. show your work ln x^2/y^3 Assuming x,y AND z are positive use properties of logariths to write the expression as a single logarithmĮvaluate log b, given that log b 2 = 0.3562 and log b 5 = 0.8271 (sorry I had no clue how to type this in math format!)ĬONDENSE INTO THE LOG OF A SINGLE QUANTITY: (1) Base 7 2/3 log( z - 2 ) (2) 2 ln8 + 5 ln( z - 4 ) (3) Base 4 1/2 + 6 logxĬalculate how you would make 0.5L of a 0.5M (500mM) acetate buffer at a pH of 4.7. Use the properties of logarithms to write the expression as a sum or difference of logarithms or multiples of logarithms. Hence or otherwise solve the equation 2 log base 2 (x+15) - log base 2 x =6 Solve the simultaneous equations log x base 2-log y base 4=4, log (x-2y)base 2=5
