Step-by-step explanation:
Figure are significant if they are a number greater than 0, if they're after a decimal place, or if they're a 0 in between significant numbers
190 has 2 sig figs
1.8 has 2 sig figs
26 has 2 sig figs
206 has 3 sig figs
thus, the answer is 206
5,000,000 because that is half of 10,000,000
If you are dividing powers with the same integral base, you will be subtracting the exponents.
5^4 / 5^2 = 5^4-2 = 5^2.
