Question

simplify :-
3-5x10-5 X 925.
5-7 x 6-5​

Answer 1

Answer:    (210•310)

Step-by-step explanation:

STEP 1

:

1.1     6 = 2•3

(6)5 = (2•3)5 = 25 • 35

Equation at the end of step

1

:

                25

 (((35)•(105))•————)•(25•35)

               (57)

STEP 2

:

Equation at the end of step

2

:

               25

 (((35)•(105))•——)•(25•35)

               57

STEP 3

:

           25

Simplify   ——

           57

Raising to a Power:

3.1    52   divided by   57   = 5(2 - 7) = 5(-5) = 1/55

Equation at the end of step

3:

                     1

 (((35) • (105)) • ————) • (25•35)

                   3125

STEP 4:

4.1     10 = 2•5

(10)5 = (2•5)5 = 25 • 55

Equation at the end of step

4

:

                       1

 (((35) • (25•55)) • ————) • (25•35)

                     3125

STEP 5:

Equation at the end of step

5

:

                     1

 ((35 • (25•55)) • ————) • (25•35)

                   3125

STEP 6:

Canceling Out:

6.1      Canceling out  55 as it appears on both sides of the fraction line

Equation at the end of step

6

:

 7776 • (25•35)

STEP 7:

Multiplying exponents:

7.1    25  multiplied by  25   = 2(5 + 5) = 210

Multiplying exponents:

7.2    35  multiplied by  35   = 3(5 + 5) = 310
