Sorry if these seem really simple but the answers i have put are wrong lol

x*x*x = x^3

y*y*y*y*y = y^ 5

hope it helps

a) x^3  (x is being multiplied by itself 3 times)

b) y^5  (y is being multiplied by itself 5 times)

answer rather than having to add and subtract the measurements of the semi-circle, notice that the semicircle to the left of ad is actually identical in area to the blank semicircle-shaped space to the left of bc. so if we transferred the red semicircle into the blank space, we would end up with a square of side length 24 cm. the area of a square is s^2 = 24^2 = 676 cm^2.

u also answered this so i think u would know but i am here to

put in or use mine
