import static java.lang.Math.pow;

Sure, you just need to call Math.pow(...), as it's a static method in the Math class:
for (int i = 0; i < n; i++) {
functionG[i] = Math.pow(1.25, i);
}
Note that I've changed it to use i rather than n as the second argument.
You could also get your original code to compile using:
import static java.lang.Math.pow;
in the import statements at the top of your code. See the Java Language Specification, section 7.5.3 for details of how this works.

June 23, 2025 - The method returns a double value representing the result of base raised to the power of exponent. Special cases include returning NaN for invalid operations, Infinity for overflow conditions, and specific handling for zero and one values. This example demonstrates the fundamental usage of the Math.pow() method with basic integer exponents:

Then you use result = Math.pow(a, b); but the variables a and b have not been initialized. You never get your exponent from the keyboard input. So my advice to you is to start over and add only one or a few lines at a time, then see if the program compiles.

When it's a power of 2 keep in mind that you can use a simple and fast shift expression: 1 << exponent
For example:
22 = 1 << 2 = (int) Math.pow(2, 2)
210 = 1 << 10 = (int) Math.pow(2, 10)
For larger exponents (over 31) use long instead:
232 = 1L << 32 = (long) Math.pow(2, 32)
BTW, in Kotlin you have shl instead of <<:
(Java) 1L << 32 = 1L shl 32 (Kotlin)

Integers are only 32 bits. This means that its max value is 2^31 -1. As you see, for very small numbers, you quickly have a result which can't be represented by an integer anymore. That's why Math.pow uses double.
If you want arbitrary integer precision, use BigInteger.pow. But it's of course less efficient.
