3(mx-1) = 3a(mx-2) হলে, x এর মান কত?

3^(mx-1) = 3a^(mx-2) হলে, x এর মান কত?

A 2/m

B 2M

C M/2

D কোনোটিই নয়

Correct Answer: Option A

3(mx-1) = 3a(mx-2)

Or, 3(mx-1)/ 3 = a(mx-2)

Or, 3(mx-1-1) = a(mx-2)

Or, 3(mx-2) = a(mx-2)

Or, (3/a) (mx-2) = 1

Or, (3/a) (mx-2) = (3/a)0

অর্থাৎ, (mx-2)= 0

(mx-2)= 0

Or, mx = 2

Or, x = 2/m
