Is -1/2n + 1 1/2n+3-n equivalent to 3? Explain plz

1 answer:

8 0

No, you can combine like terms like this (-1/2 + 11/2 -1)n +3 =3. Then you just simplify to see if the two sides of the equation match. You get 4n+3=3 which is not always true so the original equation is not true.

Feel free to ask any questions.

How do you right 0.0001 in expanded form

kirza4 [7]

The expanded form of the number 0.0001 is $\bold{\frac{1}{10000}}$ .

<u>SOLUTION: </u>

Given that, we have to write 0.0001 in expanded form.

Expanded form or expanded notation is a way of writing numbers to see the math value of individual digits. When numbers are separated into individual place values and decimal places they can also form a mathematical expression.

Now, take the given number 0.0001

As there are no other digits except 0 in front of 1 our work is simplified.

Expanded form will be $\frac{1}{10000}$

Hence, the expanded form of the number 0.0001 is $\frac{1}{10000}$ .
