PLEASE HELP ASAP
If set A = {3,4,7,9) and set B = [8, 9, 10, 11), then AUB is

Step-by-step explanation:

AuB={3,4,7,9}U{8,9,10,11}

is should be y = 5x

step-by-step explanation:

correct me if im wrong

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!
