Technically, this is already solved! √7/8 has a rational denominator, 8, √7 can't be simplified unless you actually calculate √7, and you cannot simplify the expression by squaring the numerator or denominator because you would change the value of the expression (it's like having 3/4 and squaring 3 and 4. You'd have 9/16, which is a totally different number).In conclusion, your answer is √7/8 since it can't be simplified, but if you calculate the root, you would end up with an irrational number roughly equal to 0.330718914...~ AzalerPS: You can use the character map to type the radical symbol.
