Answer 2

$8p {q}^{2} (2 {p}^{2q} - 3p + 5q + 7pq^{2} )$

So we will put the value of p = 1.7 and q = 0.4 in place of p and q

$8 \times 1.7 \times (0.4) ^{2}( ( {2 \times 1.7)}^{2 \times 0.4} - 3 \times 1.7 + 5 \times 0.4 + 7(1.7)(0.4) ^{2} )$

$13.6 \times 0.16( {3.4}^{0.8} - 5.1 + 2 + 11.9 \times 0.16$

$2.176(2.66 - 5.1 + 2 + 1.904)$

$2.176 \times 1.464$

$3.703104$

The answer is 3.703104
