Answer 1

Answer:

• 1106 . . . or
• 3499

  see below for explanation

Step-by-step explanation:

The first four digits of the root depend on whether the exponent in scientific notation is even or odd.

If it is even, then the mantissa of the root is ...

$N \approx\sqrt{1.2243648607}\approx 1.106\dots$

If it is odd, then the mantissa of the root is ...

$N \approx\sqrt{12.243648607}\approx 3.499\dots$
