Answer:

All you need to remember is the rules

Step-by-step explanation:

Let us remember

a to the m power x a to the nth power is = a to the m+n power. (add the exponents)

And

a to the m power ÷ a to the nth power is = a to the m-n power. (subtract the exponents) So

14 to the -4 power x 14 to the 7 power= 14 to the -4+7 which is equal to 14 to the 3rd power

11C4 × 11C5

\binom{11}{4}   \times  \binom{11}{5}  =  \frac{11 \times 10 \times 9 \times 8}{4 \times 3 \times 2 \times 1}   \times  \frac{11 \times 10 \times 9 \times 8 \times 7}{5 \times 4 \times 3 \times 2 \times 1}  = 330 \times 462 = 152460
