(y^-1/2)^4
rewrite the expression in the form of y^n
i need

1/(Y^2) or if you want in y^n is y^2

apply exponents law (a^b) ^c  = a^b c

take off the parenthesis

1/2 · 4

1 · 4/(2)

4/2

divide it

4/2= 2, nevertheless it become -2

y^-2

1/(y^2)

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%

answer: the distance

step-by-step explanation:

to calculate the distance d of a line segment with endpoints (x1, y1) and (x2, y2) use the formula d (x2 x1)2 (y2 y1)2. to calculate the midpoint of a line segment with endpoints (x1, y1) and (x2, y2) use the formula
