1/3(4+18)-2 to the second power

3.33333333333

or

10          

 —— = 3.33333

 3            

Step by step solution :

Step  1  :

Equation at the end of step  1  :

  1          

 (— • 22) -  22

  3          

Step  2  :

           1

Simplify   —

           3

Equation at the end of step  2  :

  1          

 (— • 22) -  22

  3          

Step  3  :

Rewriting the whole as an Equivalent Fraction :

3.1   Subtracting a whole from a fraction

Rewrite the whole as a fraction using  3  as the denominator :

         22     22 • 3

   22 =  ——  =  ——————

         1        3  

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

Adding fractions that have a common denominator :

3.2       Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

22 - (22 • 3)     10

—————————————  =  ——

      3           3

Final result :

 10          

 —— = 3.33333
