Question

Sravya explained that 10 must be subtracted from 6570 to make
perfect square. Is it correct. Do you agree with her ? Explain.​

Answer 1

Answer:

Without a calculator I can quickly say no.

The only perfect squares that end in 0 are squares of multiples of 10.

Perfect squares of multiples of 10 will end with two zeros, because 10⋅10=100.

6560 ends in a single zero, and so you know immediately it cannot be a perfect square.

I hope this helped you! Mark as the brainliest answer if it does. As I am so hesitant to get brainly answer. ;( So, even though I answer correctly, and with detail and spend my time, I don't get brainliest. :)
