If $$ x=\sqrt{(1.96)}-\sqrt{(0.04)}$$ then the value of x is

The product of two whole numbers is 37. The square root of the difference of the numbers is

Simplify the following equation
$$ {\sqrt{(1-sin^{2}θ) ÷{(1-cos^{2}θ)}}}$$

If 1.5 a=0.04 b then $$ {b-a\over b+a}$$.

If a² + a + 1 = 0 then the value of a⁹ is. 

If the average of 11, 23 and x is 40, then what is the value of x?

2x + 4y – 8xy -1 =?

The value of $${4- \sqrt{0.04} \over 4+\sqrt{0.4} } $$  is closed to
