a)4^10

b)4^21

c)16^10

d)16^21

which expression is equivalent to the one shown below ?

x^7/ x^3

a)0

b)4

c)x^4

d)x^10

Answer 1 :

Option A - 4^10

Step-by-step explanation:

4^3*4^7

If bases are same and are multiplied then power will be added.

( 4 ) ^ 3 + 7

( 4 ) ^ 10

Thus, option A is correct.

Answer 2 :

Option C - x^4

Step-by-step explanation:          

x^7/ x^3

If bases are same and divided then powers will be subtracted

( x ) ^ 7 - 3

( x ) ^ 4

Hence, option C is correct .

part a

x     y

0     8

1     7.5

2     7

3     6.5

4     6

5     5.5  

for every hour i deducted .5 inches from the length of the candle

part b

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value

x       y

0       8

1       7.6

2       7.2

3       6.8
