The correct Answer is:
To evaluate \( (48)^2 \) using suitable identities, we can use the identity for the square of a binomial, specifically \( (a - b)^2 = a^2 - 2ab + b^2 \). ### Step-by-Step Solution: 1. **Rewrite 48 in terms of a nearby round number**: We can express 48 as \( 50 - 2 \). \[ (48)^2 = (50 - 2)^2 \] 2. **Apply the binomial square identity**: Using the identity \( (a - b)^2 = a^2 - 2ab + b^2 \), we set \( a = 50 \) and \( b = 2 \). \[ (50 - 2)^2 = 50^2 - 2 \cdot 50 \cdot 2 + 2^2 \] 3. **Calculate each term**: - Calculate \( 50^2 \): \[ 50^2 = 2500 \] - Calculate \( 2^2 \): \[ 2^2 = 4 \] - Calculate \( 2 \cdot 50 \cdot 2 \): \[ 2 \cdot 50 \cdot 2 = 200 \] 4. **Combine the results**: Substitute these values back into the expression: \[ (50 - 2)^2 = 2500 - 200 + 4 \] Now perform the arithmetic: \[ 2500 - 200 = 2300 \] \[ 2300 + 4 = 2304 \] 5. **Final result**: Therefore, \[ (48)^2 = 2304 \]
