Simplify 1/a + 1/b

how do you even go about solving this problem? ? i'm so plz me you : 3

1/A + 1/B

= B/AB + A/AB

= (A + B)/AB

Step-by-step explanation:

There's nothing to solve, because you haven't been told what the expression is actually equal to.

Circumstances will determine whether 1/A + 1/B or (A + B)/AB is the most convenient expression.

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.

or

step-by-step explanation:

we need to solve for 'x' the following equation:  

we have that:

⇒

⇒ ⇒

factorizing, we get that:

  ⇒

then, the solutions are: or
