change the number to a decimal with just the numbers higher than 0 in this case
it would be 2.21 then count how many times you moved the decimal over to achieve that number ( in this case 20) since you moved the decimal to the left the power would be positive 20
so the scientific notation is 2.21 x 10^20

Hey there!
In order to find the area of a triangle, you need to:
<em>Multplipy the base by the height</em>
<em>Then you take that product and multiply it by 1/2 (basically divide it by 2)</em>
<em>Then you get your area!</em>
Base: 19
Height: 12
19 x 12
228
228 x 1/2
228/2
114
So the area of this triangle is

Step-by-step explanation:
Answer:
3966
Step-by-step explanation:
Use order of operations to solve this problem:
- Parentheses
- Exponents
- Multiply (Left to right)
- Divide (Left to right)
- Addition
- Subraction
In your case, there are no parentheses or exponents, so we can skip right the the multiply and divide step. The first multiplication is 98*63=6174. The next step is to do 32*69=2208. Then you minus 6174-2208=3966.
Hope this helps!
