Which exponential expression represents the numerical expression 7.7.7.7 ?

7^4

Step-by-step explanation:

We are multiplying 7 together 4 times

7*7*7*7

The exponent represents how many times we are multiplying it together.

7^4

Step-by-step explanation:

A mathematical expression written in the form is said to be an exponential expression where is a constant called the base and is a variable.

Here we are given a numerical expression 7.7.7.7 which can also be converted into an exponential expression where base would be 7 while the value of its exponent will be 4 since the number 7 is occurring 4 time.

Therefore, the exponential expression will be

1. minimum

2. 6400

3. eight

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
