Is this

evaluate the following expression using the values given.

find 2x2 − 2z4 + y2 − x2 + z4 if x = −4, y = 3, and z = 2.

answer blank 1: 9

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.

have a nice day!
