Answer:
3.8 = 38/10 = 19/5
Step-by-step explanation:
You can always represent a terminating decimal number as the ratio of integers. Count the number of decimal places, and multiply and divide it by 10 to that power. If you like, you can reduce the resulting fraction. 3.8 has 1 decimal place, so our chosen power of 10 is 10¹.
3.8 = (3.8×10¹)/(10¹) = 38/10 = 19/5
Is means equal to.

Answer:
A
Step-by-step explanation:
Both are ten numbers apart
Answer:
3125*k^9 + y^3 is an integer my closure property.
but 5^(1/3) is not an integer, which forces z to be irrational.
Note that there is no way an integer value can rationalize 5^(1/3)
Step-by-step explanation:
x^3 = 25z^3 - 5y^3
x^3 = 5 ( 5z^3 - y^3)
x = (5 ( 5z^3 - y^3) )^(1/3) must be an integer
= 5^(1/3) * (5z^3 - y^3)^(1/3)
Then (5z^3 - y^3)^(1/3) = 25*k^3 for some integer k
5z^3 - y^3 = 15625*k^9
5z^3 = 15625*k^9 + y^3
z^3 = 3125*k^9 + (1/5)*y^3
z = ( 3125*k^9 + (1/5)*y^3 )^ ( 1/3)
