Answer 1

Hey there

It’s quite easy my friend—

•How we find the root by estimation.

1. We know that cube root means 3rd root of a number. So with this we can reason that we will divide the numbers into pairs of 3 for estimation.

Hence— 421 And 875

Further we get the answer as 75.

Hence your answer shall be that

75x-7(we know that 343 cube root=7)

So final answer=-525
