Q. Rewrite the expression in the form xn.Write the exponent as an integer, fraction, or an exact decimal (not a mixed number).4x32x2=□
Identify expression and root type: Identify the expression and the type of root.The expression is 4x32x2, which means we have a fourth root of a fraction where the numerator is x squared and the denominator is x raised to the power of two-thirds.
Rewrite as exponent: Rewrite the fourth root as an exponent.The fourth root of a number can be written as raising that number to the power of 1/4.So, 4(x32x2) can be written as (x32x2)1/4.
Simplify expression inside root: Use the properties of exponents to simplify the expression inside the root.When dividing like bases with exponents, we subtract the exponents: xa/xb=xa−b.So, (x2)/(x(2)/(3)) simplifies to x2−(2/3).
Calculate exponent: Calculate the exponent.2−32=36−32=34.So, x(32)x2 simplifies to x34.
Apply fourth root: Apply the fourth root to the simplified expression.Now we have (x4/3)1/4.When raising a power to a power, we multiply the exponents: (xa)b=xa∗b.So, (x4/3)1/4 simplifies to x(4/3)∗(1/4).
Calculate new exponent: Calculate the new exponent.(34)×(41)=124=31.So, (x34)41 simplifies to x31.
Write final answer: Write the final answer.The expression 4x32x2 rewritten in the form xn is x31.
