Which statement describes what these four powers have in common? 4^0 (-2)^0 (1/3)^0 a. all the powers have a value a value of 0 because the exponent is zerob. all the powers have the value of 1 because the exponent is zero

Option B is correct

all the powers have the value of 1 because the exponent is zero

Step-by-step explanation:

Using the exponent rule:

for any real number a.

Given that:

⇒all the powers have the value of 1 because the exponent is zero

Therefore, the  Statement describes what these four powers have in common is, all the powers have the value of 1 because the exponent is zero

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.

1 is c

2 is a

3 is a
