Examples with solutions for Absolute value: Using powers

Exercise #1

∣33−5∣= |3^3 - 5| =

Step-by-Step Solution

First, calculate 33 3^3 . That is, 3×3×3=27 3 \times 3 \times 3 = 27 .

Next, subtract 5 from 27: 27−5=22 27 - 5 = 22 .

Finally, the absolute value of 22 is ∣22∣=22 |22| = 22 since it is already a positive number.

Answer

22 22

Exercise #2

∣62−10∣= |6^2 - 10| =

Step-by-Step Solution

First, calculate 62 6^2 . That is, 6×6=36 6 \times 6 = 36 .

Next, subtract 10 from 36: 36−10=26 36 - 10 = 26 .

Finally, the absolute value of 26 is ∣26∣=26 |26| = 26 since it is already a positive number.

Answer

26 26

Exercise #3

∣52−24∣= |5^2 - 24| =

Step-by-Step Solution

First, calculate 52 5^2 . That is, 5×5=25 5 \times 5 = 25 .

Next, subtract 24 from 25: 25−24=1 25 - 24 = 1 .

Finally, the absolute value of 1 is ∣1∣=1 |1| = 1 since it is already a positive number.

Exercise #4

∣23−5∣= \left|2^3 - 5\right| =

Step-by-Step Solution

The expression ∣23−5∣ \left|2^3 - 5\right| represents the absolute value of the result of subtracting 5 from 23 2^3 .

Calculate the power: 23=8 2^3 = 8 .

Subtract the numbers: 8−5=3 8 - 5 = 3 .

The absolute value of 3 is 3 3 , so the answer is 3 3 .

Exercise #5

∣(9−3)2∣= \left|(9 - 3)^2\right| =

Step-by-Step Solution

The expression ∣(9−3)2∣ \left|(9 - 3)^2\right| represents the absolute value of the square of (9 - 3).

Calculate the difference: 9−3=6 9 - 3 = 6 .

Then compute the square: 62=36 6^2 = 36 .

The absolute value of 36 36 is 36 36 .

Answer

36 36

Exercise #6

∣32−7∣= |3^2 - 7| =

Step-by-Step Solution

The expression inside the absolute value is 32−7 3^2 - 7 . Calculate 32 3^2 :
32=9 3^2 = 9 .

Then, subtract 7 from 9:
9−7=2 9 - 7 = 2 .

The absolute value of 2 is 2, so the expression evaluates to 2. Therefore, |3^2 - 7| = 2.

Answer

4 4

Exercise #7

∣4−31∣= |4 - 3^1| =

Step-by-Step Solution

First, calculate 31 3^1 :
31=3 3^1 = 3 .

Then, subtract 3 from 4:
4−3=1 4 - 3 = 1 .

The absolute value of 1 is 1, so the expression evaluates to 1. Therefore, |4 - 3^1| = 1.
