Answer 1

Answer:

8pq2(2p2q−3p+5q+7pq2)

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} )8×1.7×(0.4)2((2×1.7)2×0.4−3×1.7+5×0.4+7(1.7)(0.4)2)

13.6 \times 0.16( {3.4}^{0.8} - 5.1 + 2 + 11.9 \times 0.1613.6×0.16(3.40.8−5.1+2+11.9×0.16

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

2.176 \times 1.4642.176×1.464

3.7031043.703104

The answer is 3.703104
