Step by step solution :

Step  1  :

1.1     6 = 2•3

(6)-5 = (2•3)(-5) = (2)(-5) • (3)(-5)

Equation at the end of step  1  :

                  125  

 (((3-5)•(10-5))•—————)•((2)(-5)•(3)(-5))

                 (5-7)

Step  2  :

Equation at the end of step  2  :

                   125  

 (((3-5)•(10-5))•———————)•((2)(-5)•(3)(-5))

                 (5)(-7)  

Step  3  :

                  1

Divide  125  by  ——

                 57

Raising to a Power :

3.1    53  multiplied by  57   = 5(3 + 7) = 510

Equation at the end of step  3  :

 (((3-5) • (10-5)) • 510) • ((2)(-5)•(3)(-5))

Step  4  :

4.1     10 = 2•5

(10)-5 = (2•5)(-5) = (2)(-5) • (5)(-5)

Equation at the end of step  4  :

 (((3-5) • ((2)(-5)•(5)(-5))) • 510) • ((2)(-5)•(3)(-5))

Step  5  :

Equation at the end of step  5  :

 (((3)(-5) • ((2)(-5)•(5)(-5))) • 510) • ((2)(-5)•(3)(-5))

Step  6  :

Multiplying exponents :

6.1    25  multiplied by  25   = 2(5 + 5) = 210

Multiplying exponents :

6.2    35  multiplied by  35   = 3(5 + 5) = 310

Final result :

    3125              

 ————————— = 0.00005  

 (210•310)
