Answer 2

Answer:

a)

(1/4+1/8) * (1/3-1/9) / 1/12= $5^{x}$

(3/8) (2/9) / 1/12= 5^{x}

(6/72) / 1/12 = 5^{x}

6/72 * 12/1 = 5^{x}

72/72 = 5^{x}

1 = 5^{x}

5^{0} = 5^{x}

then

x = 0

b)

7^{16}   .    5^{24}

$7^{16} =(7^{2})^{8} = 49^{8}$

and

$5^{24} =(5^{3})^{8} = 125^{8}$

now we should compare between $49^{8} and 125^{8}$

so $125^{8} \geq 49^{8} \\so \\\\7^{16\leq } 5^{24}$
