Question

Am nevoie urgent de răspuns.

Answer 1

log2^1024=x^2
log2^1024=log2^2^2x
1024=2^2x
2^10=2^2x
10=2x
x=10/2=5

Se pare ca m-am inselat. Urmatoarea rezolvare este buna : 
log2^1024=x^2
log2^1024=log2^2^x^2
1024=2^x^2
2^10=2^x^2
10=x^2
x=+- radical din 10

Answer 2

[tex]\it log_2 1024 =x^2 \Leftrightarrow log_2 2^{10} =x^2 \Leftrightarrow 10\cdot log_2 2 =x^2\Leftrightarrow x^2 =10 \\\;\\ \it \Leftrightarrow x = \pm \sqrt{10}[/tex]
