Answer 1

Answer:

1²x + {57+68} +{56+68}

Answer - 6789

Answer 2

Answer:

7

Step-by-step explanation:

$\frac{p-1}{p}=2[Given]\\\\=>p-1=2p\\=>p-2p=1\\\\=>-p=\frac{1}{2}\\\\=>p=\frac{-1}{2}$

$\frac{9p^{3} -1}{p^{3}}\\\\=>\frac{9(\frac{-1}{2})^{3}-1}{(\frac{-1}{2}) ^{3} }\\\\=> \frac{9-1-1\times8}{8\times 1}\\\\=>7$
