** Answer: **
When one number is expressed as a power of another number,
the power to which the second number has been raised is called
its exponent.
In
32 = 2^{5}, 27 = 3^{3}, 5 = 25 ^{½}
the components are 5,3, and ½. Many calculators have
an exponential key labeled x y for raising numbers to a power.**
