Questions that require substituting values into expressions with rational or integer exponents and simplifying using index laws to obtain a numerical answer.
102. If $A = \sqrt[6]{4\sqrt[3]{16}}\left(\dfrac{1}{2}\right)^{-\frac{1}{3}}$, then $(2A)^{-\frac{4}{3}}$ equals which of the following? (1) $0.25$ (2) $0.5$ (3) $0.75$ (4) $1$
If $x = 1 + \sqrt[5]{2} + \sqrt[5]{4} + \sqrt[5]{8} + \sqrt[5]{16}$, then the value of $\left(1 + \frac{1}{x}\right)^{30}$ is (A) 2 (B) 5 (C) 32 (D) 64
While teaching the topic of exponents, Teacher Kerem stated that the expression $a^{b^{c}}$ cannot be written without parentheses in this way, because the expressions $a^{\left(b^{c}\right)}$ and $\left(a^{b}\right)^{c}$ can have different values, and explained this situation with an example. Accordingly, which of the following could be the example given by Teacher Kerem? A) $a = 1, b = 2, c = 3$ B) $a = 2, \quad b = 1, \quad c = 3$ C) $a = 2, \quad b = 2, \quad c = 2$ D) $a = 3, \quad b = 0, \quad c = 3$ E) $a = 3, \quad b = 2, \quad c = 1$
