Answer:
If,
[tex] {3}^{x} = 2187 \\ = > x = 7 \\ = = = = = = = [/tex]
But 3^x ≠ 21875,if x is a whole number.

Answer: x = log10(21875)/log10(3)
Step-by-step explanation:
3x=21875
3 to the power of x equals 21875
Take the log of both sides
log10(3x)=log10(21875)
Rewrite the left side of the equation using the rule for the log of a power
x•log10(3)=log10(21875)
Then, Isolate the variable x by dividing both sides by the constant term log10(3)
x = log10(21875)/log10(3)
