### Question

What is $({33/18})^0.18 × ({33/18})^x = ({33/18})^0.3$?

**A**

0.12.

**B**

0.62.

**C**

1.62.

**D**

2.12.

**Soln.**

**Ans: a**

We can simplify the given expression to $({33/18})^{0.18 + x} = ({33/18})^0.3$. The bases are equal, so the powers should also be equal. Hence $0.18 + x = 0.3$ which gives x = 0.12.
