Somebody please solve this!!!​
Alex73 [517]

Answer:

See below.

Step-by-step explanation:

We know that

                              tanA + tan B

tan (A + B)     =     ---------------------                       

                               1 - tanAtanB

Substituting for A + B

tan (A + B) = tan pi/4 = 1.

            tanA + tan B

So        ------------------   =    1

             1 - tanAtanB

Therefore   tanA + tan B =   1 - tanAtanB.

Alika [10]

Answer:

$$\sum_{n=1}^{5} 6(2^{n-1}) $$

Step-by-step explanation:

6 + 12 + 24 + 48 + 96 =

= 6 + 6 * 2 + 6 * 4 + 6 * 8 + 6 * 16

= 6 + 6 * 2^2 + 6 * 2^2 + 6 * 2^3 + 6 * 2 * 4

= 6 * 2^(n - 1)

$$\sum_{n=1}^{5} 6(2^{n-1}) $$
