The double implication "if and only if" is graphically represented by an arrow pointing in both direction, so the correct writing is
![p \iff q](https://tex.z-dn.net/?f=%20p%20%5Ciff%20q%20)
Answer:
5^1
Step-by-step explanation:
(law of indices - fractional powers)
after converting all the numbers to this form:
![\frac{5^{{\frac{2}{3} } } * 5^{\frac{1}{2} } }{5^{\frac{1}{6} } } \\](https://tex.z-dn.net/?f=%5Cfrac%7B5%5E%7B%7B%5Cfrac%7B2%7D%7B3%7D%20%7D%20%20%7D%20%2A%20%205%5E%7B%5Cfrac%7B1%7D%7B2%7D%20%7D%20%7D%7B5%5E%7B%5Cfrac%7B1%7D%7B6%7D%20%7D%20%7D%20%5C%5C)
combine using law of indices:
5^(2/3+1/2-1/6) = 5^1
