6. Solve:
(a)
(b)
If ab = 2, bc = 6 and ca = 3 then find the value of a.
If a+b=5, b+c=6 and c + a = 7 then find the value of a.
[ Hint: Adding them, a +b+b+c+c+a = 5+6+7]

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!

i'll be glad to : )
