Question

raiz cuadrada de 10 elevado a 2 - × elevado a 2=8​

Answer 1

Respuesta:

√(10)^(2-x)^2 = 8 ; √(10) = 10^(1/2)

10^(1/2)^(2-x)^2 = 8

10^((1/2×2)(2-x)) = 8

10^(2/2(2-x)) = 8

10^(1(2-x)) = 8

10^(2-x) = 8

Log 10 (10^(2-x)) = Log 10(8)

(2-x)×(Log10(10)) = Log 10 (8)

(2-x)×1 = Log10(8) ; Log10(8) = 0,903 ( Aproximadamente )

2-x = 0,903

2-x+x = 0,903+x

2 = 0,903+x

2-0,903 = 0,903+x-0,903

1,097 = x

x = 1,097
