Exponential word problems are problems involving something that increases at a constant rate. Exponential expressions can also be use to describe three-dimensional shapes. Your students will write expressions involving exponents that describe the given shape situations. They will also write and solve equations involving exponents to solve ...

Using the power of a power property of exponential functions, we can multiply the exponents: 63x+2 = 62x+2 But we know the exponential function 6x is one-to-one. Therefore the exponents are equal, 3x+ 2 = 2x+ 2 Solving this for x gives x = 0 . Example 1.2 Solve 25 2x = 125x+7. Solution: Note that 25 = 52 and 125 = 53. Therefore the equation is ...
