[tex]\(\square\)[/tex]



Answer :

Let's work through the problem step-by-step and simplify the expression to find the value of \( x \).

1. Innermost group, apply the product of powers:
[tex]\[ \left[3^{-1}\right]^3 \][/tex]
When you raise a power to a power, you multiply the exponents:
[tex]\[ (3^{-1})^3 = 3^{-1 \cdot 3} = 3^{-3} \][/tex]

2. Apply the power of a power:
[tex]\[ 3^{-3} \][/tex]
We have already simplified to \( 3^{-3} \) in the previous step.

3. Apply the negative exponent:
[tex]\[ \frac{1}{3^3} \][/tex]
A negative exponent means that we take the reciprocal of the base with a positive exponent.

4. Simplify:
[tex]\[ \frac{1}{3^3} = \frac{1}{27} \][/tex]
Here, \( 3^3 \) equals 27.

So, the value of \( x \) in the simplified expression is:
[tex]\[ x = 27 \][/tex]
Thus, [tex]\( x = 27 \)[/tex].
