3 to the power of 2 divided by 3 plus 2 to the power of 2 times 7 minus 20 divided 5

3^2/3+2^2x7-20/5

Do inverse operations first.

9/3+28-4

3+28-4

Answer = 27

Step-by-step explanation:

answer: a.   one is a factor of every whole number since every number is divisible by itself.

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!
