Find the value of x:
2³ × 3⁴ × 1080 ÷ 15 = 6^x

The smallest 4- digit number which is a perfect square is 

$$ {4\over 5}×[{1\over 2}\ of\ 25]+12÷{3\over 4}-32=?$$

(0.04)^-1.5 on simplification gives: 

If (a + b):(b + c):(c + a) = 7:6:5 and a + b + c = 27, then what will be the value of 1/a: 1/b :1/c?

Find the value of given expression. 

[76 – {90 ÷ 5 ⨯ (24 – 36 ÷ 3) ÷ 3}] 

$$3\sqrt{ {72.9\over0.4096}}$$ is equal to : 

The value of   $$ {(0.03)^2 - (0.01)^2}\over 0.03-0.01 $$
