The probability of compound events combines at least two simple events, either the union of two simple events or the intersection of two simple events.
The divide and simplify of the equation √36 x⁴ / √9 x⁶ will result to 
Let's begin by simplifying the equation;
Simplify the equation by finding the square root of both 36 and 9
The square root of 36= 6
The square root of 9= 3
= 
The above equation can also be written as;
= 
The next step is to solve the powers, that is,
= 
Cancel out 6 by 3 and get 2
The result is,
= 
The final submission result is,
=

Answer:
Let the price of the maths book be m and price of the novel book be n
Given that,
Total cost of the books is $54
The price of math book is $8 more than 3 times the price of novel book.
we get,
The system of equation as,

Hence the system of equation to determine the price of the maths and novel book is,
