Rewrite 1/2 x 1/2 as an exponential expression with a base of 2

2^-2

Step-by-step explanation:

According to the properties of integer exponents, 1/a^n = a^-n.

So 1/2 x 1/2 = 1/2^2 = 2^-2.

1/2 x 1/2 can be rewritten as the exponential expression 2^-2.

Edmentum answer

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%
