Answer 2

Corrected question :

Write equivalent java expression for,

• | a⁵ - √b |

Explaination :

• Here we would be using pow method, sqrt method and abs method . pow method would be used because it returns the value of first argument raised to second argument, here first argument is a and second argument is 5 to which it is raised.
• Whereas in the second condition sqrt method will be used because the sqrt is being returned of b
• And abs method will be used because the whole expression is returning the absolúte value of the argument

Final Answer :

• Math.abs (Math.pow (a , 5) - Math.sqrt (b))

Additional Information :
