Answer 1

Answer:

Answer is 9/2.

Step-by-step explanation:

$(8 \times 12 \div 9 \times 8 ) {}^{2} \times \frac{81}{32}$

8 and 8 will be reduced to 1 and 12 by 9 gives 4/3

then ,

$( \frac{4}{3} ) {}^{2} \times \frac{81}{32}$

$\frac{16}{9} \times \frac{81}{32}$

we know : 9*9 = 81

16*2 = 32

so ,

$= \frac{9}{2}$

$\bf( \frac{8 \times 12}{ {3}^{2} \times {2}^{3} } ) {}^{2} \times \frac{81}{32}$

$\bf (\frac{ {2}^{3} \times 12 }{ {3}^{2} \times {2}^{3} } ) {}^{2} \times \frac{ {3}^{4} }{32}$

$\bf ( \frac{12}{ {3}^{2} } ) {}^{2} \times \frac{ {3}^{4} }{32}$

$\bf \frac{144}{ {3}^{4} } \times \frac{ {3}^{4} }{32}$

$\bf \frac{144}{32}$

$\bf \frac{9}{2}$
