Final answer:
To simplify (w^((3)/(8)))^(7), multiply the exponents to get w^(21/8).
Step-by-step explanation:
To simplify (w^((3)/(8)))^(7) without parentheses, we need to multiply the exponents. In this case, 3/8 is being raised to the power of 7, so we multiply 3/8 by 7, which gives us 21/8. Therefore, the simplified expression is w^(21/8).
