Question

por favor resolva a equação:
25x³-100=0​

Answer 1

$\LARGE\tt{} {25x}^{3} - 100 = 0 \\\LARGE\tt{} {25x}^{3} = 100 \\ \LARGE\tt{} {25x}^{3} \div 25 = 100 \div 25 \\ \LARGE\tt{} {x}^{3} = 100 \div 25 \\ \LARGE\tt{} {x}^{3} = 4 \\ \LARGE\tt{}x = \sqrt[3]{4} \\ \\ {\large\boxed{\boxed{  { \LARGE \tt x = \sqrt[3]{4} }}}}$

Bons estudos

Answer 2

Resposta:

$\red{ x = \sqrt[3]{4} }$

Explicação passo-a-passo:

$\blue{25x {}^{3} - 100 = 0 } \\25x {}^{3} - 100 = 0 \\25x {}^{3} - 100 + 100 = 0 + 100 \\ 25x {}^{3} = 0 + 100 \\ 25x {}^{3} - 100 + 100 = 0 + 100 \\ 25x {}^{3} = 100 \\ 25x {}^{3} - 100 = 0 \\ 25x {}^{3} = 100 \\ 25x {}^{3} \div 25 = 100 \div 25\\x {}^{3} = 100 \div 25 \\ 25x {}^{3} \div 25 = 100 \div 25 \\ x {}^{3} = 4 \\ 25x {}^{3} = 100 \\ x {}^{3} = 4 \\ x = \sqrt[3]{4} \\ \purple{resposta} \\ \red{x = \sqrt[3]{4} }$
