Question

Find the value (-10m^2n^6)×(-20mn^15) for m=1.2 and n= -1​

Answer 1

Answer:

$10m ^{2} {n}^{2} \times ( - 20mn ^{15} ) \\ = 10 ({1.2})^{2} ( - 1 )^{6} \times (\ - 20) \times 1.2 \times ( - 1) ^{15} \\ = 10 \times 1.44 \times 1 \times ( - 20) \times 1.2 \times ( - 1) \\ = 14.4 \times 24 \\ = 345.6$

Answer 2

Answer:

-10×1.2²×-1×-20×1.2×-1

= -10×12/10×12/10×-1×-20×11/10×-1

= -72/5×-24×-1

= -1728/5

= -345.6
