Given a = 4, b = -2 and c = 8, evaluate 3abc.

3(4)(-2)(8) is what the equation looks like all you have to do is multiply all these numbers so 3 times 4 equals 12 and 12 times -2 equals -24 then lastly multiply -24 by 8 which gives you the product of -192.

just sum

10 + 10 = 20

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!
