Question

СРОЧНО!!!

Решите ур-е:
$frac{1}{32} x^{5} + frac{1}{243}=0$

Answer 1

$frac{1}{32}x^5 + frac{1}{243} =0\\ frac{1}{32}x^5 =- frac{1}{243}\\x^5= - frac{1}{243}:frac{1}{32}\\x^5=-frac{1}{243}* frac{32}{1}\\x^5=- frac{2^5}{3^5}\\x^5=(- frac{2}{3} )^5\\x=- frac{2}{3}$

Answer 2

1/32*x^5+1/243=0
(1/2)^5*x^5=-(1/3)^5
x^5=-(2/3)^5
x=-2/3
