Question

2.3^x = 10.3¹² + 8.27⁴

Answer 1

2.3^x=10.3¹²+8.27⁴

=>2.3^x=5.2.3¹²+4.2.(3³)⁴

=>2.3^x=5.2.3¹²+4.2.3¹²

=>2.3^x=(5+4).2.3¹²

=>2.3^x=9.2.3¹²

=>2.3^x:2=9.3¹²

=>3^x=3².3¹²

=>3^x=3¹⁴

=>x=14

Vậy x=14.

Answer 3

2.3x=10.312+8.274

=>2.3x=5.2.312+4.2.(33)4

=>2.3x=5.2.312+4.2.312

=>2.3x=(5+4).2.312

=>2.3x=9.2.312

=>2.3x:2=9.312

=>3x=32.312

=>3x=314

=>x=14

Vậy x=14.
