Chapter P, Problem 1E
To determine

a.

To compute:

The given expression.

Expert Solution

Answer to Problem 1E

Solution:

The value of the expression 17×3 is 51.

Explanation of Solution

Given:

The expression is 17×3.

Approach:

Multiplication:

A mathematical operation performed on a pair of numbers in order to derive a third number

called a product.

The operation of multiplying some number a by some number b may be symbolized in six

different ways:

a×b

ab

a*b

ab

a(b)

(a)(b)

Calculation:

The given expression is 17×3.

Here, the symbol × represents multiplication. We have to multiply 17 by 3 times, we get 51.

(i.e.,) 17×3=51.

Final statement:

Therefore, the value of the expression 17×3 is 51.

To determine

b.

To compute:

The given expression.

Answer to Problem 1E

Solution:

The value of the expression 17/3 is 5.67.

Explanation of Solution

Given:

The expression is 17/3.

Approach:

Division:

The operation of division can also be expressed in several different ways as follows,

a/b or ab.

Calculation:

The given expression is 17/3.

Here, the symbol “/” represents division.

Hence, we have to divide 17 by 3.

We get 5.66666...

To round off, look at the digit in 1000th place.

Since, the digit is greater than 5, round up it as 5.67.

Thus, the value of the given expression 17/3 is 5.67.

Final statement:

The value of the expression 17/3 is 5.67.

To determine

e.

To compute:

The given expression.

Expert Solution

Answer to Problem 1E

Solution:

The value of the expression (42)2 is 1764.

Explanation of Solution

Given:

The expression is (42)2.

Approach:

Square of a number:

Square of a number is to multiply the number by itself. This operation is symbolized as X2, which is the same thing as (X)(X).

Calculation:

The given expression is (42)2.

We know that, X2=(X)(X)

Substitute X=42 in the above expression,

(42)2=(42)(42)(42)2=1764

Hence 42 squared is 1764.

i.e., (42)2=1764.

Final statement:

The value of the expression (42)2 is 1764.

To determine

f.

To compute:

The given expression.

Expert Solution

Answer to Problem 1E

Solution:

The value of the expression 113 is 10.63.

Explanation of Solution

Given:

The expression is 113.

Approach:

Square root of a number:

The square root of a number is the value that, when multiplied by itself, results in the original number. This operation is symbolized as X.

Calculation:

The given expression is 113.

Here, the symbol “   ” represents square root.

Hence, we have to find the square root of the number 113.

We get 10.63014...

To round off, look at the digit in 1000th place.

Since, the digit is less than 5 round down it as 10.63.

Thus, the value of the given expression 113 is 10.63.

Final statement:

The value of the expression 113 is 10.63.
