solution by radicals meaning in Hindi

Examples

1. The quintic was almost proven to have no general solutions by radicals by Paolo Ruffini in 1799, whose key insight was to use permutation " groups ", not just a single permutation.
2. The Abel Ruffini theorem states that such a solution by radicals does not exist, in general, for equations of degree at least five . �variste Galois showed that an equation is solvable in radicals if and only if its Galois group is solvable.
3. And to Bo Jacoby, yes the formula is basically useless, but if someone wants to solve a'poorly behaved'Quartic by hand, and they want a solution by radicals, they often follow something like Ferrari's method through w / number in place of those unwieldy expressions, correct ? talk ) 20 : 23, 30 July 2009 ( UTC)
