Question 135

$$(3\times3\div\frac{1}{3}of\frac{1}{3})^{\frac{1}{4}}+3.4-4.4=?$$

Solution

BODMAS rule is to be followed while evaluating the expression.

$$1/3$$ of $$1/3$$ is $$1/9$$

$$3/(1/9) = 3*9 = 27$$

$$27*3 = 3^{4}$$

$$(3^{4})^{\frac{1}{4}} = 3$$

$$ 3+ 3.4-4.4 = 3-1 =2$$

Option A is the right answer.
