Question

find m if (3) ^-7+(3) ^-10=(3) ^2m-1​

Answer 1

Step-by-step explanation:

Since the bases of the exponents are same, since all are 3, we cancel and proceed our further calculation with the exponents...

$= > ( - 7) + ( - 10) = (2m - 1) \\ \\ = > - 17 = 2m - 1 \\ \\ = > - 17 + 1 = 2m$

$= > - 16 = 2m \\ \\ = > m = \frac{ - 16}{2} = - 8$

Therefore, m = -8
