Question

Successive subtraction of 400 cube root

Answer 1

we subtract 57 from 400

Answer 2

Answer:

400 - 1 = 399

400 - 1 = 399399 - 7 = 392

400 - 1 = 399399 - 7 = 392392 - 19 = 373

373 - 37 = 336

336 - 61 = 275

275 - 91 = 184

184 - 127 = 57

The next number to be subtracted from 57 is 271. But 271 is greater than 57. So, 57 must be added from 7 to get a perfect cube.

57 + 7 = 64

Also, 64 = 4 × 4 × 4. 3√64 = 4
