Question

Calcule o x : Logx10=1/2 b- log2 x/2=4

Answer 1

Resposta:

Explicação passo-a-passo:

$a)\\ \log x10={1\over2}\\ \\ x^{{1\over2}}=10\\ \\ \sqrt{x} =10\\ \\ (\sqrt{x} )^2=10^2\\ \\ x=100\\ \\ S=\{100\}\\ \\ b)\\ \log_2{x\over2}=4\\ \\ {x\over2}=2^4\\ \\ {x\over2}=16\\ \\ x=16.(2)\\ \\ x=32\\ \\ S=\{32\}$
