nadezda [96]
Beef to pork.....ratio 3:1....added = 4.....this is basically saying that 3/4 of the total meat is beef and 1/4 of the total meat is pork...and the total meat is 3 lbs.

3/4(3) = 9/4 = 2 1/4 lbs of beef
1/4(3) = 3/4 lbs of pork <===

Calculate a and b if
const2013 [10]

Notice that

7^{2014} - 7^{2012} = 7^{2012} \bigg(7^2 - 1\bigg) = 7^{2012} \times 48 = 2^4 \times 3 \times 7^{2012}

12=2^2\times3, so

\dfrac{7^{2014}-7^{2012}}{12} = 2^2 \times 7^{2012}

Then taking the positive square root gives

\sqrt{\dfrac{7^{2014}-7^{2012}}{12}} = \sqrt{2^2 \times 7^{2012}} = 2\times7^{1006}

so \boxed{a=2} and \boxed{b=1006}.
