Although it is generally agreed that a young child in primary school should not be left alone, age is not the only consideration. Some children might function well at home alone, while others might not be ready to assume the responsibility of self-care. Parents must make an informed decision based on their own child.
general method to solve this kind logarithm on both sides step 1 use the rules of logarithms to rewrite the left side and the right side of the equation to a single logarithm step 2 cancel the log step 3 solve the expression let s look at a specific ex log 5 x log 2 3 log 5 6 step 1 rewrite both sides as single logs
Let x and y be any real numbers: log x = y x = log inv (y) = 10^y Example: pH =13.22 = -log [H+] log [H+] = -13.22 [H+] = inv log (-13.22) = 10^(-13.22) [H+] = 6.0 x 10-14 M FINDING ANTILOGARITHMS using a calculator (also called Inverse Logarithm) Sometimes we know the logarithm (or ln) of a number and must work backwards to find the number itself. This is called finding the antilogarithm or inverse logarithm of the number. To do this using most simple scientific calculators, enter the number, press the inverse (inv) or shift button, then press the log (or ln) button. It might also be labeled the 10x (or ex) button.
