I would start by converting everything into decimal, as it makes it a LOT easier to understand. So, you should be able use a calculator to convert the square roots and fractions into decimal. Let's start. Square root 12 is equivalent to 3.46 (to 2 decimal places) Square root 9 is 3 (you should know that because 3 × 3 = 9) 12 is already in decimal so it's just 12 3.56, 4.03 and 4.2 are also in decimal so you leave them Square root 17 is 4.12 (to 2 decimal places) Square root 2 is 1.41 (also 2 decimal places) 1/2 is the same as 0.5 (once again, you should know that) And 3/2 is the same as 3 ÷ 2, which is 1.5. So in order of least to greatest, it's: 1/2, square root of 2, 3/2, square root of 9, square root of 12, 3.56, 4.03, square root of 17. 4.2 and finally 12. Hope this helps :)

postnew [5]

I'm going to assume that's a multiplication not a decimal point.

\sqrt{81 \cdot 49} = \sqrt{9 \cdot 9 \cdot 7 \cdot 7} = \sqrt{63 \cdot 63} = 63

Answer: 63
