Q. Which expressions are equivalent to (b2)91 ?Choose all answers that apply:A (b−91)2B (b91)2C (b21)9D None of the above
Determine Exponent Simplification: We need to determine which of the given options are equivalent to the expression (b2)(91). According to the properties of exponents, when we raise a power to another power, we multiply the exponents. So, (b2)(91) simplifies to b2∗(91), which is b92.
Evaluate Option A: Now let's evaluate each option to see if it simplifies to b92.Option A: (b−(91))2 simplifies to b−92, which is not equivalent to b92 because the exponent is negative.
Evaluate Option B: Option B: (b(1/9))2 simplifies to b2/9, which is equivalent to our original expression (b2)(1/9).
Evaluate Option C: Option C: (b(1/2))9 simplifies to b9/2, which is not equivalent to b2/9 because the exponent is much larger and not a reciprocal.
Evaluate Option D: Option D: None of the above is not correct because we have found that Option B is equivalent to the original expression.
