Can (5^2) and (4^3) be written as a singe power

no

Step-by-step explanation:

No,  neither the bases are the same , nor the exponents are the same, so the cannot combine them.  

a^b  where a is the base and b is the exponent

No

Step-by-step explanation:

5^2 and 4^3 can not be written as a single power because they do not have the same base, and they are not equal, as 25 does NOT equal 64.

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%

the least value out of the data shown is 5, maybe if you post a picture with it i could a little more.
