Question

9^n=49 round to the nearest ten thousandth

Answer 1

We have the following expression:
 9 ^ n = 49
 We apply logarithm to both sides of the expression:
 log9 (9 ^ n) = log9 (49)
 By properties of logarithm we have:
 n = log9 (49)
 n = 1.771243749
 round to the nearest ten thousandth:
 n = 1.7712
 Answer:
 n = 1.7712
