Answer :
Answer:
To find the squares of \( 6^2 + 7^2 + 42^2 \), let's calculate each square individually and then sum them up.
1. Calculate \( 6^2 \):
\[ 6^2 = 6 \times 6 = 36 \]
2. Calculate \( 7^2 \):
\[ 7^2 = 7 \times 7 = 49 \]
3. Calculate \( 42^2 \):
\[ 42^2 = 42 \times 42 = 1764 \]
4. Sum the squares:
\[ 6^2 + 7^2 + 42^2 = 36 + 49 + 1764 \]
5. Perform the addition:
\[ 36 + 49 = 85 \]
\[ 85 + 1764 = 1849 \]
Therefore, the sum of squares \( 6^2 + 7^2 + 42^2 \) is \( \boxed{1849} \).
