Question 227

What will come in the place of both question marks (?) in the following question?

$$\frac{(?)^{1.8}}{32}=\frac{16}{(?)^{1.2}}$$

Solution

Let the number in the question mark be '$$x$$'

So, $$\frac{x^{1.8}}{32}=\frac{16}{x^{1.2}}$$

So, $$x^{1.8+1.2}=32*16=8^3$$

So, $$x^3 = 8^3$$

Hence, $$x=8$$
