Q. Select the answer which is equivalent to the given expression using your calculator.10+6−594−50−5694−350−35694−50+5694−350+356
Rationalize Denominator: To find the equivalent expression, we need to rationalize the denominator of the given expression (−5)/(10+6). This means we need to eliminate the square root from the denominator.
Multiply by Conjugate: To rationalize the denominator, we multiply the numerator and the denominator by the conjugate of the denominator. The conjugate of (10+6) is (10−6).
Simplify Numerator: Now, multiply the numerator and the denominator by the conjugate: (10+6−5)×(10−610−6)=(10+6)×(10−6)−5×(10−6).
Simplify Denominator: Simplify the numerator: −5×(10−6)=−50+56.
Final Simplified Expression: Simplify the denominator using the difference of squares formula: (10+6)×(10−6)=102−(6)2=100−6=94.
Compare with Answer Choices: Now we have the simplified expression: (−50+56)/94.
Compare with Answer Choices: Now we have the simplified expression: (−50+56)/94.Comparing the simplified expression with the answer choices, we find that the equivalent expression is (−50+56)/(94).
