For y=x^6, at x=7 and dx=0.01, what is the approximate dy?
y=x^6 में x=7 पर dx=0.01 हो, तो approximate dy क्या होगा?
Show answer and explanation
Correct Answer
A. 50421 / 50
ExplanationStep 1: in differentials, dy≈f'(x)dx. Step 2: f'(x)=6x^5; substituting x=7 and dx=0.01 gives dy≈50421/50. Step 3: tip: for small change, use derivative × change.
Step 1: differentials में dy≈f'(x)dx होता है। Step 2: f'(x)=6x^5; x=7 और dx=0.01 रखने पर dy≈50421/50। Step 3: tip: small change questions में derivative × change use करें।
