Answer: (51ab^2)/(20c)

STEP

1

:

Equation at the end of step 1

((17•(a3))•(b2)) ((18•(b4))•(c3))

————————————————•————————————————

((15•(b3))•(c2)) ((23a2•b)•c2)

STEP

2

:

Equation at the end of step

2

:

((17•(a3))•(b2)) ((2•32b4)•c3)

————————————————•—————————————

((15•(b3))•(c2)) 23a2bc2

STEP

3

:

(2•32b4c3)

Simplify ——————————

23a2bc2

Dividing exponential expressions :

3.1 b4 divided by b1 = b(4 - 1) = b3

Dividing exponential expressions :

3.2 c3 divided by c2 = c(3 - 2) = c1 = c

Dividing exponents:

3.3 21 divided by 23 = 2(1 - 3) = 2(-2) = 1/22

Equation at the end of step

3

:

((17•(a3))•(b2)) 9b3c

————————————————•————

((15•(b3))•(c2)) 4a2

STEP

4

:

Equation at the end of step

4

:

((17•(a3))•(b2)) 9b3c

————————————————•————

((3•5b3)•c2) 4a2

STEP

5

:

Equation at the end of step

5

:

(17a3 • b2) 9b3c

——————————— • ————

(3•5b3c2) 4a2

STEP

6

:

17a3b2

Simplify —————————

(3•5b3c2)

Dividing exponential expressions :

6.1 b2 divided by b3 = b(2 - 3) = b(-1) = 1/b1 = 1/b

Equation at the end of step

6

:

17a3 9b3c

————— • ————

15bc2 4a2

STEP

7

:

Dividing exponential expressions :

7.1 a3 divided by a2 = a(3 - 2) = a1 = a

Dividing exponential expressions :

7.2 b3 divided by b1 = b(3 - 1) = b2

Dividing exponential expressions :

7.3 c1 divided by c2 = c(1 - 2) = c(-1) = 1/c1 = 1/c

Final result :

51ab2

—————

20c
