Final answer:
The expression '4 to the power of 5' means 4 multiplied by itself four more times, resulting in 4 raised to the 5th power. Similarly, 'x to the power of 5' would be x multiplied by itself four additional times, represented as x^(5).
Step-by-step explanation:
Understanding integer powers is essential for comprehending expressions like x to the power of 5. The expression '4 to the power of 5' means 4 × 4 × 4 × 4 × 4. Similarly, to express 'x to the power of 5', you would write x × x × x × x × x. In such a case, each instance represents the base, x, multiplied by itself a total of five times. Moreover, when discussing powers of 10, remember that exponents are added when you multiply powers of 10 together, so for example, 10² × 10³ equals 10&sup5;. This is similarly applied to any base, including the variable x.
