Answer 1

Răspuns:

$\bf a)~~4^{8}\cdot 4^{7}= 4^{8+7}=\green{\boxed{\bf 4^{15}}}$

$\bf b)~~9^{17}: 9^{13}= 9^{17-13}=\blue{\boxed{\bf 9^{4}}}$

$\bf c)~~\big(19^{3}\big)^{10}= 19^{3\cdot10}=\purple{\boxed{\bf 19^{30}}}$

$\bf d)~~2^{5}\cdot3^{5}= \big(2\cdot3\big)^{5}=\red{\boxed{\bf 6^{5}}}$

Answer 2

Răspuns:

a)4⁸×4⁷= 4⁸⁺⁷=4¹⁵=(2²)¹⁵=2²ˣ¹⁵=2³⁰

b)9¹⁷:9¹³ =9¹⁷⁻¹³=9⁴=(3²)⁴=3²ˣ⁴=3⁸

c) (19³)¹⁰= 19³ˣ¹⁰=19³⁰

d)2⁵×3⁵=(2·3)⁵=6⁵
