2â = 3^b = 6^-c , what is value of 1/a +1/b +1/c? • Let us assume a value which we can equate with all these values. (use log table for solving this question). • Let us take all these values equal to 1. thus value of A, B and C are equal to Zero. Thus the answer is Zero. • We can also assume these values to be equal to 6. • A = 2.6, B =1.65 and C = -1 • Now putting these values: ½.6 + 06/21/1.65 9/09 ERSCHOOOL CENTRE F 56 – 1 AFTwww.afterschoool.tk
