I assume you mean:
[x^(5/6)]/[x^(1/6)]
The rule for dividing similar bases with different exponents is:
(a^b)/(a^c)=a^(b-c)
In this case we have:
x^(5/6-1/6)
x^(4/6)
x^(2/3)
Answer: 54
Step-by-step explanation: Step 1 i checked how many each one has and multiplied it by all of the numbers there were there by using a plus the hours are 54
Both of them together have 690 because you subtract 152 from 421 so...
421-152=269
Then add 269 to 421
421+269=690
Its not a negative number but a positive number
