Correct Answer - Option 1 : 70
Given:
\(\sqrt {700 × \sqrt {42 + \sqrt {42 + \sqrt {42 + ...\infty } } } } \)
Concept used:
Simplification
Calculation:
From the right hand side a series of 42 with + sign continues
Breaking 42 in two consecutive terms
⇒ 6 × 7 = 42
There is + sign in between so the greater of the two numbers is the ans
∴ Ans : 7
Further solving it we get
⇒ \(\sqrt {700 \times 7} = \sqrt {4900} \)
∴ Ans : 70
