(a)
Compute the given signed number
Answer to Problem 32A
Value of the given number is,
Explanation of Solution
Given:
Calculation:
Here digit
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 an odd number. Therefore the product will be a negative number.
Hence the value of the given number is,
(b)
Compute the given signed number
Answer to Problem 32A
Value of the given number is, -0.83
Explanation of Solution
Given:
Calculation:
Here digit (-1.038) is indicated as power of 5 i.e. fifth power of (-1.038)
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 a odd number. Therefore the product will be a negative number.
Hence the value of the given number is, -0.83
(c)
Compute the given signed number
Answer to Problem 32A
Value of the given number is, 0.0032
Explanation of Solution
Given:
Calculation:
Here digit (17.66) is indicated as power of 2 i.e. square of (17.66)
All the digits in the given problem have positive signs. As there is no negative sign in the given number .So the product will also be a positive sign.
Hence the value of the given number is, 0.0032
(d)
Compute the given signed number
Answer to Problem 32A
Value of the given number is, -1.748
Explanation of Solution
Given:
Calculation:
Here digit (-0.83) is indicated as power of 3 i.e. cubic power of (-0.83)
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, -1.748
(e)
Compute the given signed number
Answer to Problem 32A
Value of the given number is, -0.000728
Explanation of Solution
Given:
Calculation:
Here digit (-6.087) is indicated as power of 4 i.e. fourth power of (-6.087)
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 4 which is a even number. Therefore the product will be a positive number.
Hence the value of the given number is, -0.000728
