{4 }^(2) * 25 / √(25 - 15) ​

Question

`{4 }^(2) * 25 / √(25 - 15)`
​

Answer 1

The answer is 126.58
You first double the 4 which is 16, then you multiply the 16 by 25 to get 400. Next, you have to subtract 25 from 15 to get 10. Then, you square root the 10, becoming 3.16
Finally, you divide the 400 by 3.16 to have the final answer: 126.58
