Answer 2

hi mate,

here to methods to find

solution:

√324 = √3*3*3*3*2*2 = 3*3*2 = 18

( * ) sign used for multiplication.

Every square number can be expressed as a sum of successive odd natural numbers starting from 1.

324-1=323

323-3=320

320-5=315

315-7=308

308-9=299

299-11=288

288-13=275

275-15=260

260-17=243

243-19=224

224-21=203

203-23=180

180-25=155

155-27=128

128-29=99

99-31=68

68-33=35

35-35=0

hence to get 0 we subtracted 18 odd no's

hence square root is 18

i hope it helps you.
