Answer:
x = -2.5
Step-by-step explanation:
3^(4x-5)=(1/27)^(2x+10)
We are working with exponents
We can rewrite 1/27 as 3^-3
3^(4x-5)=(3^-3)^(2x+10)
Now we know that a^b^c = a^(b*c)
3^(4x-5)=3^( -3* (2x+10))
3^(4x-5)=3^( -6x -30)
The bases are the same so the exponents must be the same
4x-5 = -6x-30
Add 6x to each side
4x-6+6x = -6x-30+6x
10x-6 = -30
Add 5 to each side
10x-5+5 = -30 +5
10x = -25
Divide by 10
10x/10 = -25/10
