Question

Scrieți sub formă de putere .​

Answer 1

Răspuns:

= a⁹b³  x  b⁸ / a⁴ = a⁵b¹¹

Answer 2

Răspuns:

$a^{5}b^{11}$

Explicație pas cu pas:

$\displaystyle a^9b^3\cdot \left(\frac{b^4}{a^2}\right)^2 = a^9b^3\cdot \frac{\left(b^4\right)^2}{\left(a^2\right)^2} = a^9b^3\cdot \frac{b^{4\cdot 2}}{a^{2\cdot 2}} =$

$\displaystyle =a^9b^3\cdot \frac{b^8}{a^4} = \frac{a^9}{a^4}\cdot b^3\cdot b^8 = a^{9-4}\cdot b^{3+8} =$

$= \boxed{a^{5}b^{11}}$
