Use scientific notation, and round to the nearest tenth if necessary.
Solve the permutation: `900P30`
I think the answer is `2.60037*10^88`
Solve the combination: `(50!)/((50-5)!*5!)`
I think the answer is `2118760`
Is this right?
Thank you in advance.

You are correct so far. But take note that, we need to express in scientific notation and round off to the nearest tenths.
Hence, `_900P_30=2.6xx10^8` .
Hence, `(50!)/((50-5)!*5!)=2.1xx10^6` .
I think `(900!)/(870!)`
Is this right? Should it be to the 88th power or 89th?
Thanks in advance.
