If the product of two positive fractions a and b is 15/56, find three pairs of possible values for a and b

-7/8

step-by-step explanation:

instead of subtracting you add the -6/8 and -1/8

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!
