1) Let's simplify those expressions making use of exponents rules:

Note that the exponent outside the parenthesis is 'distributed' over each term inside.
2) Similarly for the second expression we can state that:
Answer:
H. All blins are smools
Step-by-step explanation:
If all blins are meeps and all meeps are stools, that means that all blins are smools.
The constant on the right is divisible by the coefficients on the left, so two solutions are
(x, y) = (5, 0) or (0, -3)
The slope of the line is 3/5, so increaing y by 3 and x by 5 will result in another solution. One general parametric solution is then
x = 5n
y = 3n-3
_____
Integer values of n will result in integer solutions. Any value of n will yield numbers that satisfy the equation.
In general, the extended Euclidean algorithm can be used to find integer solutions. Then adding multiples of some number n to y and x in the ratio of the slope of the line will yield other solutions.
The answer is 3 because all you have to do is plug in the answer and then you have to solve the answer and go from there.
