(a)
Compute the given signed number

Answer to Problem 30A
Value of the given number is, -32
Explanation of Solution
Given:
Calculation:
Here digit (-2) is indicated as power of 5 i.e. fifth power of (-2)
Now count the number of negative signs in the given number:
1. If the sum is a even number then the product is positive.
2. if the sum is a odd number then the product is negative.
In this given number, the sum of negative signs is 5 which is an odd number. Therefore the product will be a negative number.
Hence the value of the given number is, -32
(b)
Compute the given signed number

Answer to Problem 30A
Value of the given number is, 36
Explanation of Solution
Given:
Calculation:
Here digit (-6) is indicated as power of 2 i.e. square of (-6)
Now count the number of negative signs in the given number, if the sum is a even number then the product is positive and if the sum is a odd number then the product is negative.
In this given number, the sum of negative signs is 2 which is a even number. Therefore the product will be a positive number.
Hence the value of the given number is, 36
(c)
Compute the given signed number

Answer to Problem 30A
Value of the given number is, -125
Explanation of Solution
Given:
Calculation:
Here digit (-5) is indicated as power of 3 i.e. cubic power of (-5)
Now count the number of negative signs in the given number:
1. If the sum is a even number then the product is positive.
2. if the sum is a odd number then the product is negative.
In this given number, the sum of negative signs is 3 which is a odd number. Therefore the product will be a negative number.
Hence the value of the given number is, -125
(d)
Compute the given signed number

Answer to Problem 30A
Value of the given number is, 64
Explanation of Solution
Given:
Calculation:
Here digit (-2) is indicated as power of 6 i.e. sixth power of (-2)
Now count the number of negative signs in the given number:
1. If the sum is a even number then the product is positive.
2. if the sum is a odd number then the product is negative.
In this given number, the sum of negative signs is 6 which is a even number. Therefore the product will be a positive number.
Hence the value of the given number is, 64
(e)
Compute the given signed number

Answer to Problem 30A
Value of the given number is, 2.56
Explanation of Solution
Given:
Calculation:
Here digit (-1.6) is indicated as power of 2 i.e. square of (-1.6)
Now count the number of negative signs in the given number, if the sum is a even number then the product is positive and if the sum is a odd number then the product is negative.
In this given number, the sum of negative signs is 2 which is a even number. Therefore the product will be a positive number.
Hence the value of the given number is, 2.56
