Q. (x47⋅x4)4Which of the following expressions is equivalent to the given expression assuming x is nonzero?Choose 1 answer:(A) x439(B) x11(C) x23(D) x28
Simplify inside the parentheses: First, let's simplify the inside of the parentheses by using the property of exponents that states when you multiply powers with the same base, you add the exponents.The expression inside the parentheses is x(47)⋅x4.We add the exponents: (47)+4.Since 4 can be written as 416, we have (47)+(416)=(423).So, the expression inside the parentheses simplifies to x(423).
Apply the exponent outside the parentheses: Now, we need to apply the exponent outside the parentheses, which is 4, to the simplified expression inside the parentheses.Using the property of exponents that states when you raise a power to a power, you multiply the exponents, we have (x(423))4.We multiply the exponents: (423)⋅4.The 4s cancel out, leaving us with 23⋅1=23.So, the expression simplifies to x23.
Compare with answer choices: We can now compare the simplified expression to the answer choices.The expression we found is x23, which matches answer choice (C).
