Answer 2

Answer:

we have,

$5 {}^{2} -( \frac{1}{4} ) {}^{ - 2} \times( \frac{3}{4} ) {}^{ - 2}$

we have to make all the powers positive

so, we will take reciprocals of the fraction so that powers becomes pisitive,

$5 \times 5 - (4) {}^{2} \times (\frac{4}{3} ) {}^{2}$

$= 25 - 4 \times 4 \times 4 \times \frac{4 \times 4}{3 \times 3}$

$= 25 - \frac{1024}{9}$

$= \frac{225 - 1024}{3}$

=-799/3

=-266.33
