it doesn't work?

anonymous · Answer

none, but the answer would be 477/32

anonymous · Answer

i mean 53/32

anonymous · Answer

hmmm thats weird

anonymous · Answer

it just doesn't work with a-d  ^^
just solve the equation

anonymous · Answer

$$2^{(5-3x)}$$ i think the first part may look like this instead

anonymous · Answer

well   can't check this one with mental math xD

anonymous · Answer

it's d       don't think i needed 6 min   just started :P

anonymous · Answer

if the problem is 2 raised to the power    (5−3x) = 1/16, then taking log[base 2] of both sides of equation LHS and RHS, gives us log[base 2] of 2 raised to the power    (5−3x) = log[base 2]1/16, then the LHS is 5-3x  and the right RHS is log[base 2](1/16).

So equation is now 5-3x = -4, then 5+4 = 3x, and 9/3 = x. Thus x = 3...
