Q. Rewrite the expression in the form k⋅zn.Write the exponent as an integer, fraction, or an exact decimal (not a mixed number).(273z2)31=□
Identify components: Understand the given expression and identify the components.The given expression is (273z2)31. We need to rewrite this expression in the form k∗zn, where k is a constant and n is the exponent.
Rewrite as exponent: Rewrite the cube root in the expression as an exponent.The cube root of a number can be written as that number raised to the power of 1/3. So, 273z2 can be written as (271/3)⋅(z2⋅(1/3)).
Simplify cube root of 27: Simplify the expression for the cube root of 27. Since 27 is 33, the cube root of 27 is 3. So, 271/3 simplifies to 3.
Simplify exponent for z: Simplify the exponent for z. The exponent for z is 2×(1/3), which simplifies to 2/3. So, z2×(1/3) simplifies to z2/3.
Apply outer exponent: Apply the outer exponent to the simplified expression.Now we have (3∗z2/3)(1)/(3). When we raise a product to an exponent, we raise each factor to that exponent: 3(1)/(3)∗(z2/3)(1)/(3).
Simplify 3 raised to 1/3: Simplify the expression for 3 raised to the power of 1/3. Since 3 raised to the power of 1/3 is the cube root of 3, which is just 3, this part of the expression remains 3.
Simplify exponent for z: Simplify the exponent for z. When we raise an exponent to another exponent, we multiply the exponents. So, (z2/3)(1)/(3) simplifies to z(2/3)∗(1/3), which is z2/9.
Combine constants and exponent: Combine the constants and the simplified exponent for z. The final expression is 3z2/9.
