If 22 is coded as SQRT484, then 29 is coded as

CBRT1331

SQRT721

SQRT841

CBRT19683

✅ Correct Option: 3

The code SQRT484 represents 22.

Examining the relationship:

$22^2 = 484$

$\sqrt{484} = 22$

The pattern codes a number $n$ as SQRT( $n^2$ ).

Applying this pattern to 29:

$29^2 = 841$

Therefore, 29 is coded as SQRT841.

Checking the options:

Option 1: CBRT1331 $= \sqrt[3]{1331} = 11$

Option 2: SQRT721 $= \sqrt{721} \approx 26.85$

Option 3: SQRT841 $= \sqrt{841} = 29$ ✓

Option 4: CBRT19683 $= \sqrt[3]{19683} = 27$

Therefore, the answer is Option 3: SQRT841.
