Verified answer
4ˣ⁺³ = √(8ˣ⁺¹⁵)-------------------- √ (kedua sisi dikuadratkan)
(4⁽ˣ⁺³⁾)² = 8ˣ⁺¹⁵
2²⁽²ˣ⁺⁶⁾ = 2³⁽ˣ⁺¹⁵⁾
2⁴ˣ⁺¹² = 2³ˣ⁺⁴⁵ ===> 4x + 12 = 3x + 45
x = 33
semoga jelas dan membantu ya
Verified answer
4^(x + 3) = √(8^(x + 15))Kuadratkan kedua ruas
4^2(x + 3) = 8^(x + 15)
2^4(x + 3) = 2^3(x + 15)
4(x + 3) = 3(x + 15)
4x + 12 = 3x + 45
4x - 3x = 45 - 12
x = 33
