Answer:
1.5^2 = 2.25
(it looks like 1.5 but if it's 15 then it would be 225)
Step-by-step explanation:
1.5^2 means (1.5*1.5) you multiply the number by itself by how many it says to do. So if it were 1.5^52 you would multiply 1.5 by 1.5, 52 times.
if you mean what is half of 85, it's 42.5
Answer:
Step 5
Step-by-step explanation:
The mistake is in step 5.
The previous step was
![step \: 4 : 2 + 10 \div 2](https://tex.z-dn.net/?f=step%20%5C%3A%204%20%3A%202%20%2B%2010%20%5Cdiv%202)
The order operations, PEDMAS, must be applied:
We have Addition and Division here,
Using PEDMAS, we must divide first to get:
![step \: 5 : 2 + 5](https://tex.z-dn.net/?f=step%20%5C%3A%205%20%3A%202%20%2B%205)
We can now add to get:
![step \: 6: 7](https://tex.z-dn.net/?f=step%20%5C%3A%206%3A%207)
Therefore the mistake occurred at step 5
