Step-by-step explanation:
Step 1:
Let x equal the repeating decimal you are trying to convert to a fraction.
Step 2:
Examine the repeating decimal to find the repeating digit(s).
Step 3:
Place the repeating digit(s) to the left of the decimal point.
Step 4:
Place the repeating digit(s) to the right of the decimal point.
Step 5:
Using the two equations you found in step 3 and step 4, subtract the left sides of the two equations. Then, subtract the right sides of the two equations
As you subtract, just make sure that the difference is positive for both sides.
Answer:
A.The answer four square root of two plus ten is irrational because the sum of a rational number and irrational number is an irrational number.
Step-by-step explanation:
Given the question as 4√2 + 5√4 the sum is
4√2 + 5*√4
4√2 + 5*2
4√2 + 10
Putting an irrational number in decimal form, it goes on forever without repeating.
4*√2 +10 = 4× 1.41421356237 +10
=15.6568542495----------------which irrational
