Which of the following results in a sum or a product that is rational? choose all that apply.
a. pi times six
b. startroot 3 endroot plus startroot 5 endroot
c. 4 + 6
d. 3 point modifyingabove 15 with bar times 4.6
e. startroot 64 endroot times startroot 25 endroot

The correct options are C, D and E.

Step-by-step explanation:

Consider the provided information.

We need to find the results in a sum or a product that is rational.

Consider the provided options.

Option A) π × 6

π × 6 = 18.8495559215...

The decimal expansion of  

the above number is neither terminate nor  

periodic.

Hence the option is incorrect.

Option B) √3 + √5

√3+√5=1.73205080757..+2.2360679775..=3.96811878507....

The decimal expansion of  

the above number is neither terminate nor  

periodic.

Hence the option is incorrect.

Option C) 4 + 6

4+6=10 which is a rational number.

The sum of two rational numbers is rational.

Hence the option is correct.

Option D) × 4.6

is a rational number because the decimal expansion is repeating and 4.6 is a rational number because the decimal expansion is terminating.

The product of two rational numbers is rational.

Hence the option is correct.

Option E) √64 × √25

This can be written as: 8 × 5 (because √64 =8 and √25=5)

8 and 5 are rational numbers.

The product of two rational numbers is rational.

Hence the option is correct.

Thus, the correct options are C, D and E.
