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
How do you solve one half log sub 7 x equals log sub 7 20 minus 2 parenthesis log sub 7 2 plus log sub 7 5 parenthesis?
When solving this problem:1/2log7x = log720 - 2(log72 + log75)There are two things to note:lognx + logny = logn(xy)a(lognx) = lognxaUsing those two rules, we can simplify the given expression:1/2log7x = log720 - 2(log72 + log75)log7x1/2 = log720 - 2(log710)log7x1/2 = log720 - log7102log7x1/2 = log720 - log7100log7x1/2 = log7(1/5)√x = 1/5x = 1/25
