solve each without a calculator
You can now do the first two sections of DeltaMath.
x^{2}=25
2^{x}=8
3^{x-1}=27
We have solved exponential equations using the LN button, but you can also some them using some basic ideas about exponents.
If 2^{x}=64, then x=6 because 64=2^6.
Solve 5^{x+2}=125^{x-4}
Solve \left(\frac{1}{9}\right)^{x}=27^{x-3}
Solve 3^{-2x}=\left(\frac{1}{27}\right)^{x-4}
Solve 4^{2x+6}\leq64^{2x-4}
Solve 10^{5b+2}>1000
Choose all that are true
I am confident in this lesson.
I would like some assistance.
I can find the common base.
