Q. Which of the following is equivalent to (2x)3 ?Choose 1 answer:(A) 6x(B) 6xx3(C) 8x(D) 83x
Apply Exponentiation Rule: To solve this problem, we need to apply the exponentiation rule which states that (ab)c=ab∗c. In this case, a=2, b=x, and c=3.
Calculate Simplified Expression: Using the exponentiation rule, we calculate (2x)3=2x∗3.
Compare with Given Options: Simplify the expression 2x⋅3 to get 23x.
Option (A): Now we compare the simplified expression 23x with the given options to find the equivalent one.
Option (B): Option (A) is 6x, which is not equivalent to 23x because 6 is not a power of 2.
Option (C): Option (B) is 6x(x3), which is not equivalent to 2(3x) because it involves multiplication and a different base.
Option (D): Option (C) is 8x, which is not equivalent to 23x because 8x is the same as (23)x=23x, but we need the exponent to be 3x, not x.
Option (D): Option (C) is 8x, which is not equivalent to 23x because 8x is the same as (23)x=23x, but we need the exponent to be 3x, not x.Option (D) is 83x, which is equivalent to 23x because 8 is 23, so 83x is the same as 23x1, which is not the same as 23x.
