1,000 + 50 + 40 + 0.04 + 0.0002 is the number above in expanded notation.
Step-by-step explanation:
90÷0.018=5000
90÷0.18= 500
90÷1.8 = 50
90÷18 =5
90÷180 =0.5
Y × 3 = 3 / 5
y = 3 / 5×3
y = 3/15
y = 1/5
In short, Your Answer would be 1/5
Hope this helps!
Answer:

Step-by-step explanation:

Answer: Choice B

======================================================
Explanation:
The two rules we use are


When applying the first rule to the expression your teacher gave you, we can say that:

Then applying the second rule lets us say

Therefore,

-------------
In short, we just multiplied each exponent inside by the outer exponent 1/2.
So that explains why the exponents go from {1/4,16} to {1/8,8} for x and y in that exact order.
