Evaluate the expression for x = 8
x = 5

4x2=8

5x1=5

Step-by-step explanation:

Because four 2 times is 8 because 4 plus 4 is 8.

and everything multiplied by 1 is the other number.

I'm not sure if that's how you meant it.

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.
