24³×24¹⁷:24²⁰ va rogggg multtttt repedeee​

Answer 1

Răspuns:

2⁹×2¹²:2¹⁹=2²¹:2¹⁹=2²=4

17⁸×17¹³:17²¹=17²¹:17²¹=1

24³×24¹⁷:24²⁰=24²⁰:24²⁰=1

Answer 2

Salut!

2⁹ × 2¹² ÷ 2¹⁹ <=>

<=> 2⁹⁺¹² ÷ 2¹⁹ <=>

<=> 2²¹ ÷ 2¹⁹ <=>

<=> 2²¹⁻¹⁹ <=>

<=> 2² = 2 × 2 <=>

<=> 4

17⁸ × 17¹³ ÷ 17²¹ <=>

<=> 17⁸⁺¹³ ÷ 17²¹ <=>

<=> 17²¹ ÷ 17²¹ <=>

<=> 17²¹⁻²¹ <=>

<=> 17⁰ = 1

24³ × 24¹⁷ ÷ 24²⁰ <=>

<=> 24³⁺¹⁷ ÷ 24²⁰ <=>

<=> 24²⁰ ÷ 24²⁰ <=>

<=> 24²⁰⁻²⁰ <=>

<=> 24⁰ = 1
