If x=0, you have

\displaystyle\lim_{y\to0}\frac{y^3}{y^2}=\lim_{y\to0}y=0

But if y=0, you have

\displaystyle\lim_{x\to0}\frac{x^4}{x^4}=\lim_{x\to0}1=1

So the limit does not exist.

When multiplying by 10 how many spaces do you move the decimal point
shusha [124]

Answer:

If you multiply a decimal by 10, the decimal point will move one place to the right. If you divide a decimal by 10, the decimal point will move one place to the left.

Step-by-step explanation:

Multiplying a decimal by 10 increases the value of each digit by 10. Multiplying a decimal by a power of 10 increases the value of each digit by a number of times that is equivalent to that power of 10. When a digit's value is changed, that digit is moved to the appropriate place.

Answer:

  • loga b = c             ⇔   a^c = b

<u>Apply the property above:</u>

  • 1.  ln 618 = p   ⇔ e^p = 618
  • 2. ln q = 2       ⇔ e^2 = q
  • 3. ln 100 = t     ⇔  e^t = 100
  • 4. ln (e^3) = 3  ⇔  e^3 = e^3
