Question

Identify the irrational sum(s). Select all that apply
√9 +√7 (A)
2.25 +6 (B)
√16 + 1/2 (C)
10 + π (D)

Answer 1

(A) is an irrational sum
(C) is also an irrational sum
(D) is an irrational sum too

Answer 2

Answer:

(A) √9+√7

(D) 10+π

Step-by-step explanation:

We have to identify the irrational sum(s).

(A)  √9 +√7 = 3+√7

since, √7 is irrational

Hence, 3+√7 is irrational sum

(B) 2.25 +6=8.25

                 =825/100

                 =33/4

Which is a rational number  (since, it can be written in the form of p/q)

(C) √16 + 1/2 = 4+1/2

                    = 9/2

Hence, it is also a rational number

(D)10 + π it is an irrational sum since,π is irrational
