Final answer:
To find the equivalent expression for (s^6)^-3, you multiply the exponents, leading to s^(6 × -3) = s^-18, which is the same as 1/s^18.
Step-by-step explanation:
To find an equivalent expression for (s^6)^-3, we use the exponent rule, which states that when we raise a power to a power, we multiply the exponents. Applying this rule, we multiply the exponents 6 and -3:
(s^6)^-3 = s^(6 × -3) = s^-18
Therefore, the equivalent expression is s^-18, which can also be written as 1/s^18 using the negative exponent rule that states a^-n = 1/a^n.
In this case, the expression can be rewritten as s^(6*-3). This simplifies to s^-18.
Therefore, the answer is a. s^-18.
