Answer 1

Răspuns:

${3}^{19} \times {3}^{21} = {3}^{40} \\ {2}^{34} \times {2}^{43} \times {2}^{10} \times {2} = {2}^{88} \\ {5}^{23} \times {5}^{10} \times {5}^{8} = {5}^{41}$

3(la puterea x)× 3² = 3 la puterea x+2

7(la puterea x) x 7 (la puterea x) = 7 la puterea 2x

7⁴³:7²⁰ = 7 la puterea 23

29³⁷:29 = 29 la puterea 36

5¹³:5⁰ = 5 la puterea 13

2³⁷:2¹⁵:2 = 2 la puterea 21

7ⁿ+¹:7 = 7 la puterea n

3²ⁿ:3ⁿ = 3 la puterea n

5³ⁿ:5ⁿ = 5 la puterea 2n

2ⁿ+¹:2ⁿ = 2

3ⁿ:3ⁿ = 3 la puterea 0 ( adica este egal cu 1)
