10000(1+.5÷60)^(60)(5)​
Marrrta [24]

Step-by-step explanation:

hope this helps answer is at bottom.  :)

Changes made to your input should not affect the solution:

(1): "t0"   was replaced by   "t^0".  

STEP

1  

:

           dot5

Simplify   ————

            12  

Equation at the end of step

1  

:

                (dot5)

 10000 • ((1 +  ——————)60)

                  12  

STEP

2  

:

Rewriting the whole as an Equivalent Fraction :

2.1   Adding a fraction to a whole

Rewrite the whole as a fraction using  12  as the denominator :

         1     1 • 12

    1 =  —  =  ——————

         1       12  

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 :

2.2       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:

12 + dot5     dot5 + 12

—————————  =  —————————

   12            12    

Equation at the end of step

2  

:

          (dot5 + 12)

 10000 • (———————————)60)

              12      

STEP

3  

:

3.1     12 = 22•3

(12)60 = (22•3)60 = 2120 • 360

Equation at the end of step

3  

:

         (dot5 + 12)60

 10000 • —————————————

          (2120•360)  

STEP

4  

:

Dividing exponents :

4.1    24   divided by   2120   = 2(4 - 120) = 2(-116) = 1/2116

Final result :

 625 • (dot5 + 12)60

 ———————————————————

     (2116•360)
