Answer:

x=27

Step-by-step explanation:

To evaluate the expression: [(3^{-5})(3^4)]^3

Step 1:  Innermost group, apply the product of powers (a^x \times a^y =a^{x+y}

Therefore:

(3^{-5})(3^4)=3^{-5+4}=3^{-1}

We then have:

=[3^{-1}]^3

Step 2: Apply the power of a power

[3^{-1}]^3=3^{-1 \times 3} =3 ^{-3}

Step 3: Apply the negative exponent

3 ^{-3} =\dfrac{1}{3^3}

Step 4: Simplify

\dfrac{1}{3^3}=\dfrac{1}{27}

Therefore, the value of x in the simplified expression is 27.

Answer:

The joule (/ dʒ aʊ l, dʒ uː l / jawl, jool; symbol: J) is a derived unit of energy in the International System of Units. It is equal to the energy transferred to (or work done on) an object when a force of one newton acts on that object in the direction of the force's motion through a distance of one metre (1 newton metre or N⋅m). It is also the energy dissipated as heat when an electric ...
