Q. Select the equivalent expression.10s−6s−1s−21s−2s21s2
Understand the expression: Understand the given expression.We are given the expression 10(s−6s−1) and we need to simplify it to find the equivalent expression.
Simplify inside the root: Simplify the expression inside the root.The expression inside the root is s−6s−1. When dividing exponential expressions with the same base, we subtract the exponents.So, s−6s−1=s−1−(−6)=s6−1=s5.
Apply the root: Apply the root to the simplified expression.Now we have 10s5. The 10th root of s5 can be written as (s5)101.
Use power of a power rule: Use the power of a power rule.Using the power of a power rule, we multiply the exponents: (s5)101=s5∗101=s21.
Identify equivalent expression: Identify the equivalent expression.The equivalent expression is s21, which is one of the options given.
