Someone me i know x=3 but i need the steps i will give branliest answer !

x=3

Step-by-step explanation

3^{5x-9} = 1/27^{2x-8}

convert 1/27^(2x-8) to base 3

3^5x-9 = 3^ -3 (2x-8)

apply exponent rule

3^5x-9 = 3^ -3 (2x-8)

5x-9 = -3( 2x-8)

x=3

f(2x−x2)=−3x2+6x−1

step-by-step explanation:

set up the composite function and evaluate.

f(2x−x2)=−3x2+6x−1
