Answer 1

Answer:

We need to find square root of 625 by repeated subtraction method.

625−1=624

624−3=621

621−5=616

616−7=609

609−9=600

600−11=589

589−13=576

576−15=561

561−17=544

544−19=525

525−21=504

504−23=481

481−25=456

456−27=429

429−29=400

400−31=369

369−33=336

336−35=301

301−37=264

264−39=225

225−41=184

184−43=141

141−45=96

96−47=49

49−49=0

At last the answer comes out to be 0.

Here number of steps to find this is 25.

Thus square root of 625 is 25.
