Question

1) Scoateti factorii
2) Introduceti factorii

Answer 1

Răspuns:

4.  $2x^{2} yz\sqrt[5]{4xyz^{2} }$

5.   $\sqrt[3]{162x^{5} y^{7} z}$

Explicație pas cu pas:

4.

$\sqrt[5]{128*x^{11} *y^{6}*z^{7} } = \sqrt[5]{2^{5}*2^{2}*x^{10}*x*y^{5} *y *z^{5} *z^{2} } = 2*x^{2} *y*z\sqrt[5]{4*x*y*z^{2} }$

5.

$3*x*y^{2} *\sqrt[3]{6*x^{2}* y*z} = \sqrt[3]{3^{3} *x^{3} *y^{6} *6*x^{2}*y*z }$

$= \sqrt[3]{162*x^{5} *y^{7} *z}$
