Question

помогите пж 2 номер,2 пример

Answer 1

$\frac{n^{48}}{n^{19}*n^{26}}=\frac{n^{48}}{n^{19+26}}=\frac{n^{48}}{n^{45}}=n^{48-45}=n^{3}$

$1)n=0,3;=>n^3=(0,3)^3=0,3*0,3*0,3=0,027$

$2)n=-0,4;=>n^3=(-0,4)^3=(-0,4)*(-0,4)*(-0,4)=-0,064$

Answer 2

$\frac{n^{48} }{n^{19}*n^{26}}=n^{48-19-26}=n^{3}\\\\1)n=-0,3\\\\(0,3)^{3}=0,027\\\\2)n=-0,4\\\\(-0,4)^{3}=-0,064$
