Answer:

Multiple: 1 * 125 = 125

Exponentiation: 2/

5

^ 2 = 22/

52

= 4/

25

In other words - two fifths raised to the power of squared = four twenty-fifths.

Multiple: the result of step No. 1 * the result of step No. 2 = 125 * 4/

25

= 125 · 4/

1 · 25

= 500/

25

= 20 · 25/

1 · 25

= 20

Multiply both numerators and denominators. Result fraction keep to lowest possible denominator GCD(500, 25) = 25. In the following intermediate step, cancel by a common factor of 25 gives 20/

1

.

In other words - one hundred twenty-five multiplied by four twenty-fifths = twenty.

Multiple: the result of step No. 3 * 5 = 20 * 5 = 100

Exponentiation: 1/

2

^ 3 = 13/

23

= 1/

8

In other words - one half raised to the power of cubed = one eighth.

Multiple: the result of step No. 4 * the result of step No. 5 = 100 * 1/

8

= 100 · 1/

1 · 8

= 100/

8

= 25 · 4/

2 · 4

= 25/

2

Multiply both numerators and denominators. Result fraction keep to lowest possible denominator GCD(100, 8) = 4. In the following intermediate step, cancel by a common factor of 4 gives 25/

2

.

In other words - one hundred multiplied by one eighth = twenty-five halfs.

Conversion a mixed number 16 1/

2

to a improper fraction: 16 1/2 = 16 1/

2

= 16 · 2 + 1/

2

= 32 + 1/

2

= 33/

2

To find a new numerator:

a) Multiply the whole number 16 by the denominator 2. Whole number 16 equally 16 * 2/

2

= 32/

2

b) Add the answer from previous step 32 to the numerator 1. New numerator is 32 + 1 = 33

c) Write a previous answer (new numerator 33) over the denominator 2.

Sixteen and one half is thirty-three halfs

Multiple: the result of step No. 6 * 33/

2

= 25/

2

* 33/

2

= 25 · 33/

2 · 2

= 825/

4

Multiply both numerators and denominators. Result fraction keep to lowest possible denominator GCD(825, 4) = 1. In the following intermediate step, it cannot further simplify the fraction result by canceling.

In other words - twenty-five halfs multiplied by thirty-three halfs = eight hundred twenty-five quarters.

Exponentiation: 3/

4

^ 4 = 34/

44

= 81/

256

In other words - three quarters raised to the power of to four = eighty-one two-hundred fifty-sixths.

Multiple: the result of step No. 8 * the result of step No. 9 = 825/

4

* 81/

256

= 825 · 81/

4 · 256

= 66825/

1024

Multiply both numerators and denominators. Result fraction keep to lowest possible denominator GCD(66825, 1024) = 1. In the following intermediate step, it cannot further simplify the fraction result by canceling.

In other words - eight hundred twenty-five quarters multiplied by eighty-one two-hundred fifty-sixths = sixty-six thousand eight hundred twenty-five one-thousand twenty-fourths.

Exponentiation: 2/

5

^ 5 = 25/

55

= 32/

3125

In other words - two fifths raised to the power of to five = thirty-two over three thousand one hundred twenty-five.
