Final answer:
When multiplying exponentials, multiply the digit terms and add the exponents of the exponential terms.
Step-by-step explanation:
When multiplying exponentials, we multiply the digit terms as usual and add the exponents of the exponential terms. This means that if we have 4² * 4³, we would multiply 4 * 4 to get 16, and add the exponents 2 + 3 to get a final exponent of 5. Therefore, 4² * 4³ = 16⁵.
