Question

if 3^m = 1/81 , then what is the value of "m" ? ​

Answer 1

Answer:

$3 {m}^{2} = 1 \div 81 \\ 3m ^{2} = 0.0123435679 \\ m ^{2} = 0.0123435679 \div 3 \\ m ^{2} = 0.00411522633 \\ m = 0.00411522633$

Answer 2

Answer:

m = -4

Step-by-step explanation:

${3}^{m} = \frac{1}{81} \\ = > {3}^{m} = { (\frac{1}{3}) }^{4} \\ = > {3}^{m} = {3}^{ - 4} \\ = > m = - 4$
