Question

3-5 x 10-5 X125
5-7 X 6-5 exponents and powers​

Answer 1

Answer:

Step-by-step explanation:

step1:     6 = 2•3

(6)-5 = (2•3)(-5) = (2)(-5) • (3)(-5)

                  125  

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

                 (5-7)

step2:                    125  

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

                 (5)(-7)

step3:  1

Divide  125  by  ——

                 57

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

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

step4:  4.1     10 = 2•5

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

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

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

step:6  6.1    25  multiplied by  25   = 2(5 + 5) = 2

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

final result:     3125              

 ————————— = 0.00005  

 (210•310)
