Solve each exponential equation. Express irrational solutions in exact form. $2^{-x}=1.5$
Added by Brett B.
Step 1
We can do this by taking the reciprocal of both sides: $$\frac{1}{2^x} = 1.5$$ Now, we want to get rid of the fraction. We can do this by multiplying both sides by $2^x$: $$1 = 1.5 \cdot 2^x$$ Show more…
