Question

log 1/2b=-3/2 -to w ułamkach prosze o wyjaśnienia

Answer 1

log 1/2 [ b ] = - 3/2  <=> (1/2)^(-3/2) = b

b = (2/1)^(3/2) = 2^(3/2) = ( 2^3)^(1/2) = 8^(1/2) = p(8) = 2 p(2)

===========================================================

p(2) - pierwiastek kwadratowy z 2

Answer 2

log 1/2b=-3/2, czyli  1/2 do potegi -3/2=b

b=1/2 do -3/2= 2 do 3/2=√2³=√8=√(4*2)=2√2
