Which exponential expression is equivalent to 2 to the -5 times 2 to the 8th? 1. 2 to the 2nd divided by 2 to the -1
2.(2 to the third) to the -1
3. 2 to the -2 divided by 2 to the -1
4. (2 to the -1) to the 3

at least two

step-by-step explanation:

2

step-by-step explanation:

80° is the measure of gh

step-by-step explanation:

circle f is congruent to circle j

we have two circle with center f and j.

both circles are congruent. the radius of the circle would be equal.

see the attachment for the circle.

we are given ∠efd ≅ ∠gjh

therefore, arc (ed) = arc (gh)     (∴ circle f is congruent to circle j)

but ∠dfe=80°=arc (ed)

therefore, arc (gh) = 80°

thus, 80° is the measure of gh
