Question

Calculati:a) 25^10×5^30:125^16:(5^3)^0​

Answer 1

Răspuns: $\bf \purple{\underline{~5^{2}~}}$

$\bf 25^{10}\cdot 5^{30}:125^{16}:(5^3)^{0} =$

$\bf (5^{2})^{10}\cdot 5^{30}:(5^3)^{16}:5^{3\cdot 0} =$

$\bf 5^{2\cdot 10}\cdot 5^{30}:5^{3\cdot 16}:5^{0} =$

$\bf 5^{20}\cdot 5^{30}:5^{48}:5^{0} =$

$\bf 5^{20+30-48-0}=\purple{\underline{~5^{2}~}}$
