Question

Express the following as power of rational numbers. -343/512​

Answer 1

Answer:

Let y=m√x be the mth root of x. Then we can write y=x1/m which means the same thing as y=m√x. Thus we can define the power to a positive rational number: Let r=pq∈Q be a positive rational number where p∈Z≥0,q∈Z>0.
