The correct Answer is:
To evaluate \( \sqrt{9025} \), we can follow these steps: ### Step 1: Pair the digits Start by pairing the digits of the number from right to left. For 9025, we have: - Pair 1: 25 - Pair 2: 90 ### Step 2: Find the largest square less than or equal to the first pair (90) The largest perfect square less than or equal to 90 is \( 81 \) (which is \( 9^2 \)). ### Step 3: Subtract the square from the first pair Now, subtract \( 81 \) from \( 90 \): \[ 90 - 81 = 9 \] ### Step 4: Bring down the next pair (25) Now, bring down the next pair (25) next to the remainder (9): \[ 9 \, 25 \] ### Step 5: Double the quotient found so far The quotient so far is \( 9 \). Double it to get \( 18 \). ### Step 6: Find a digit (let's call it \( x \)) such that \( (18x) \times x \) is less than or equal to \( 925 \) We need to find \( x \) such that: \[ (180 + x) \times x \leq 925 \] Testing \( x = 5 \): \[ (180 + 5) \times 5 = 185 \times 5 = 925 \] This is equal to 925, so \( x = 5 \) is valid. ### Step 7: Write the complete quotient Now, the complete quotient is \( 95 \). ### Step 8: Verify the result To verify, we can multiply \( 95 \times 95 \): \[ 95 \times 95 = 9025 \] Thus, \( \sqrt{9025} = 95 \). ### Final Answer \[ \sqrt{9025} = 95 \] ---
