Examples with solutions for Absolute value: Using powers

Exercise #1

431= |4 - 3^1| =

Step-by-Step Solution

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

Then, subtract 3 from 4:
43=1 4 - 3 = 1 .

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

Answer

1 1

Exercise #2

335= |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: 275=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 #3

5224= |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: 2524=1 25 - 24 = 1 .

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

Answer

1 1

Exercise #4

6210= |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: 3610=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 #5

327= |3^2 - 7| =

Step-by-Step Solution

The expression inside the absolute value is 327 3^2 - 7 . Calculate 32 3^2 :
32=9 3^2 = 9 .

Then, subtract 7 from 9:
97=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 #6

235= \left|2^3 - 5\right| =

Step-by-Step Solution

The expression 235 \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: 85=3 8 - 5 = 3 .

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

Answer

1 1

Exercise #7

(93)2= \left|(9 - 3)^2\right| =

Step-by-Step Solution

The expression (93)2 \left|(9 - 3)^2\right| represents the absolute value of the square of (9 - 3).

Calculate the difference: 93=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
