Step-by-step explanation:
Given Find x so that 1/3 power -2 × 1/3 power -5=1/3 power 2x+1
- We need to find the value of x
- Given (1/3)^-2 x (1/3)^-5 = (1/3)^2x + 1
- . Also using exponential law we have a^m x a^n = a^m + n
- so we get (1/3)^-2 - 5 = (1/3)^2x + 1
- (1/3)^-7 = (1/3)^2x + 1
- Now since the bases are same exponents are equal
- So we can write the above equation as
- So - 7 = 2x + 1
- Or 2x + 1 = - 7
- Or 2x = - 7 – 1
- Or 2x = - 8
- Or x = - 4
