Hello May some one please help on getting the answer for number 21

Answer:
x = 3/2
Step-by-step explanation:
9^x = 27
Rewrite both terms as powers of 3
9 = 3^2 and 27 = 3^3
3^2^x = 3^3
We know that a^b^c = a^(b*c)
3^(2x) = 3^3
The bases are the same, so the exponents need to be the same
2x= 3
Divide by 2
2x/2 = 3/2
x = 3/2
