Answer:
25.
Explanation:
The first thing we must note are thr rules of significant figures:
RULES FOR SIGNIFICANT FIGURES
1. All non-zero numbers ARE significant
2. Zeros between two non-zero digits ARE significant.
3. Leading zeros are NOT significant
4. Trailing zeros to the right of the decimal ARE significant
From this, we see the total amount of sig figs in 24.790000, which is every number, To round this to two sig figs, we just need to round to two places, which ends up being the tens and ones place to the left of the decimal. The answer would then be 25., with the decimal mark to denote that there are only two sig figs.
