<span>You would do the innermost operation first, so for your first example: squaring a cubed root- you would first take the cubed root, get your answer, and square that answer. For example what's the square of the cubed root of 8? Well, the cubed root of 8 is 2. (Because multiplying 2, three times will give me 8). Since the cubed root of 8 is 2, I need to square 2 and I'll get 4.</span>
Answer:
D
Step-by-step explanation:
factor the denominators of both fractions
x² - 16 ← is a difference of squares
= (x - 4)(x + 4)
8x + 2x² ← factor out 2x from each term
= 2x(4 + x) = 2x(x + 4)
then expression is
+ 
with LCD of 2x(x + 4)(x - 4)
Answer: 4
Step-by-step explanation:
Answer: 9/25 or 36%
Step-by-step explanation:
The first time it is a probability of 3/5, and the second blue also has a prbability of 3/5. Multiply them together since it is an "and" situation, and you get 9/25. Or, in percentages, it is 60% * 60%, or 0.6 * 0.6, which is 36% or 0.36. Hope this helps!
