Error?

1=power(1,2)

2+2=power(2,2)

3+3+3=power(3,2)

4+4+4+4=power(4,2) . . . . .

x+x+x+....(x times)=power(x,2)

Differentiating w.r.t. x

1+1+1+....(x times)=2*x

=> x=2*x

=> 1=2

What's the wrong ? Can you find it?

x+x+x......is x times which is variable........hence that differeantiating step is wrong Ritesh Puri · 3 years, 4 months ago

There is "(\(x\) times)", which relies on \(x\) too, so you can't just go differentiate term by term on the left hand side. Or something similar. I've read this but cannot find it again. Ivan Koswara · 3 years, 4 months ago

Why use division property of equality in the part (x = 2x) if you can isolate the x's instead... John Ashley Capellan · 3 years, 4 months ago
