Answer» (d) 64 \(\sqrt[2]{\sqrt[3]{X\times0.000001}}\) = 0.2 \(\Rightarrow\) \(\sqrt[3]{X \times 0.000001}\) = (0.2)² = 0.04 (Squaring both the sides) \(\Rightarrow\) x x 0.000001 = (0.04)³ = 0.000064 (on taking the cube of both the sides) \(\Rightarrow\) x = \(\frac{0.000064}{0.000001}\) = 64.

\(\sqrt[2] {\sqrt[3]{X \times 0.000001}}\) = 0.2. The value of x is(a) 8(b) 16(c) 32(d) 64

Answer»

(d) 64

\(\sqrt[2]{\sqrt[3]{X\times0.000001}}\) = 0.2

\(\Rightarrow\) \(\sqrt[3]{X \times 0.000001}\) = (0.2)²

= 0.04 (Squaring both the sides)

\(\Rightarrow\) x x 0.000001 = (0.04)³ = 0.000064 (on taking the cube of both the sides)

\(\Rightarrow\) x = \(\frac{0.000064}{0.000001}\) = 64.
