3. what is the value of x?
Jawaban:
x = 4
Penjelasan dengan langkah-langkah:
[tex] \frac{ {2}^{x + 2} + {2}^{x + 4} + {?}^{x + 6} }{128} = \frac{21}{2} [/tex]
[tex] {2}^{x + 2} + {2}^{x + 4} + {2}^{x + 6} = \frac{21}{2} \times 128[/tex]
[tex] {2}^{x + 2} + {2}^{x + 4} + {2}^{x + 6} = 1344[/tex]
[tex](1 + {2}^{2} + {2}^{4} ){2}^{x + 2} = 1344[/tex]
[tex](1 + 4 + 16) {2}^{x + 2} = 1344[/tex]
[tex]21 \times {2}^{ x + 2} = 1344[/tex]
[tex] {2}^{x + 2} = \frac{1344}{21} [/tex]
[tex] {2}^{x + 2} = 64[/tex]
[tex] {2}^{x + 2} = {2}^{6} [/tex]
[tex]x + 2 = 6[/tex]
[tex]x = 6 - 2[/tex]
[tex]x = 4[/tex]
jadi, nilai x adalah 4

7. 2. Find the value of 576 byusing prime factorisation.3. Given that the primefactorisation of 21952 is 26 x73, find the value of 21952.
Jawaban:
2. 24
3. 28
Penjelasan dengan langkah-langkah:
2) 576 = 2⁶ × 3²
→ √576 = √(2⁶×3²) = 2³ × 3 = 24
*diakarpangkatkan 2 sama artinya dengan bagi pangkat bil. dalam akar dengan 2
3)³√(2⁶×7³) = 2² × 7 = 28
*diakarpangkatkan 3 sama artinya dengan bagi pangkat bil. dalam akar dengan 3
kesimpulan: suatu bilangan yang diakarpangkatkan n, sama saja dengan membagi pangkat dari faktor-faktor bilangan tersebut dengan n

12. What is the value of x in 3(x-4) =-20
Kelas 7 Matematika
Bab Persamaan Linear
3 (x - 4) = -20
3x - 12 = -20
3x = -20 + 12
x = -8/3Jawaban :
3(x-4) = - 20
3x - 12 = - 20
3x = -20 + 12
3x = -8
x = -8/3
x = - 2 2/3

(a) 27 - 2x ≤ 8
-2x ≤ -19
x ≥ 19/2
x ≥ 9,5
(b) smallest integer value of x? I'm sure it's 10 .. (maybe ¯\_(ツ)_/¯)
20. Look at the figure aboveWhat is the value of X?
Materi : Sudut
x = 180° - (55° + (180° - 83°))
