Step-by-step explanation:

A.

$49 \times 7 {}^{3} \times 100 \\ 10 {}^{3} \times 3 {}^{3} \times 7 {}^{2}$

$= 7 {}^{2} \times 7 {}^{3} \times 10 {}^{2} \\ 10 {}^{3} \times 3 {}^{3} \times 7 {}^{2}$

$= 7 {}^{3} \\ 10 \times 3 {}^{3}$

$= 343 \\ 10 \times 27$

$= 343 \\ 270$

$= 1.27$

B.

$121 \times 5 {}^{3} \\ 11 {}^{2} \times 5$
