Answer: $\frac{7}{20}$

Step-by-step explanation:

If this is asking for the probability of randomly drawing a blue marble then it'll be however many blue marbles (what you're trying to find) out of the total number of marbles

Blue marbles: 7

Total marbles: 20

$\frac{7}{20\\}$

Someone help with this please!!!!

Answer:

$10^{4} * 10^{3}=(10*10*10*10)(10*10*10) = 10^{7}\\\\10^{4}*10^{4}=(10*10*10*10)(10*10*10*10) = 10^8\\\\(10*10*10)(10*10*10*10*10)=10^3*10^5=10^8\\$

$10^{18}*10^{23}=$ (10 x 10 18 times)(10 x 10 23 times) $=10^{41}$

just as a note: when you multiply numbers with exponents and they both have the same base, all you have to do is add the exponents.

Ex: $10^{5}*10^{4}=10^{5+4}=10^{9}$
