x < 35

Let's test

1 nickel and 35 pennies. That doesn't work

4 nickel and 20 pennies. That works. Perhaps we be more precise?

Answer:

$\sqrt[7]{b^{15}}$

Step-by-step explanation:

=> $b^2*\sqrt[7]{b}$

=> $b^2*b^{1/7}$

Where bases are same, powers are to be added.

=> $b^{2+(1/7)}$

kumpel [21]

Answer:

6720

Step-by-step explanation:

The writing 8P5 represents the number of permutations of 8 elements taken 5 at a time.

First Method :

8P5 = 8 × 7 × 6 × 5 × 4

= 6720

Second Method :

$8P5=\frac{8!}{\left( 8-5\right)!}$

$=\frac{8!}{ 3!}$

$=\frac{8 \times 7 \times 6 \times 5 \times 4 \times 3!}{ 3!}$

$= 8 \times 7 \times 6 \times 5 \times 4$

$= 6720$
