Question: how to write as a radical expression?
Answer: Write the expression (x^2)^(4/3) into radical form. Note that the (x^2) is the base and the (4/3) is its exponent. Use the base law of exponents, which states that (x^m)^n equals x^(m * n). Multiply the exponent on the base by the other exponent: x^(2 * 4/3) or x^(8/3).
