Answer:
which is an irrational number
Step-by-step explanation:
Recall that the repeating decimal 0.7373737373... can be written in fraction form as:
Now, let's write the number 147 which is inside the square root in factor form to find if it has some perfect square factors:
Then, 7 will be able to go outside the root when we compute the final product requested:
This is an irrational number due to the fact that it is the product of a rational number (quotient between 511 and 99) times the irrational number
Answer:
(1)
Multiplying by 3 both sides of the equality you get that
3u is in the Span of the vectors .
(2)
That's not true, consider the following counter example.
is a linear combination of
but is NOT a linear combination of
Step-by-step explanation:
(1)
As the hint indicates, you know that
Then, if you multiply both sides of the equality by 3, you get that
And that's it. 3u is in the Span of the vectors
(2)
That's not true, consider the following counter example.
