May someone please explain to me how to do this in the easiest way? I don't really understand. Thanks❤

Ok, so 1 is a whole number.  1/5 is a fraction of 1.  So you want to subtract 1/5 from 1.  The number 1 is equal to 5/5.  So if you subtract 1/5 from 5/5 you are left with 4/5.  You do the same with the second one, just subtract 3/5 from 5/5 to get your answer.

10^8/10^4 Simplify the expression. Write your answer as a power.
Andru [333]
<h3>Answer:   10^4</h3>

This is an exponential expression with 10 as the base and 4 as the exponent.

=============================================

Explanation:

We're dividing 10^8 over 10^4. When dividing like this, we subtract the exponents (numerator minus denominator). The bases must be the same value and they stay at the same value for the final answer as well.

The new exponent is 8-4 = 4 which is how we arrive at the answer 10^4.

Side note: 10^4 = 10,000 = ten thousand

Hello!

To solve this you have to find the ratio between the two cylinders

Cylinder 1 height is 30
Cylinder 2 height is 20

this is a 30:20 ratio

This can be reduced to a 3:2 ratio

Now you look for one that are also equal to 3:2

3 * 7 = 21
2 * 7 = 14

The answers are 3:2 and 21:14

Hope this helps!
