WebThe logarithm of a multiplication of x and y is the sum of logarithm of x and logarithm of y. log b ( x ∙ y) = log b ( x) + log b ( y) For example: log b (3 ∙ 7) = log b (3) + log b (7) The product rule can be used for fast multiplication calculation using addition operation. WebSolution: Here logx is main factor whose bases are different. Put in continuous like 21, 31, 41... up to 20th term. Required result is log7x (sum of 21 natural numbers - 1) = 230. or log7x(320) = 230. ∴ 7 = x.
