Question : 7 of 100

Marks: +1, -0

\sqrt{33124} \times \sqrt{2601} - (83)^2

(?)^2+(37)^2

Solution:

Concept:

Simplify the square roots first, then solve the resulting equation for

(?)^2

Explanation:

\sqrt{33124}=182

because

182^2=33124

\sqrt{2601}=51

because

51^2=2601

So,

182 \times 51 = 9282

Also,

(83)^2=6889

and

(37)^2=1369

The equation becomes:

9282 - 6889 = (?)^2 + 1369

2393 = (?)^2 + 1369

(?)^2 = 2393 - 1369

(?)^2 = 1024

? = \sqrt{1024} = 32

Since

32

is not listed in the options, the correct choice is None of these.

Answer:

?=32

, so option E. None of these.
