Dwayne starts at the surface of the water and swims to -25 feet. From there he swims +10 feet to see the fish and then back down

d1i1m1o1n [39]

(-25) + 10 + (-5) = -20 feet is his current position. To reach zero, he should add 20 feet to his altitude.

If p and q are distinct primes. Find the number of positive divisors of<br> p^2 * q^2

kkurt [141]

Answer:

Step-by-step explanation:

We know that for $p^mq^n$ where p and q are different prime numbers the number of positive divisors are (m+1) (n+!)

We have given $p^2q^2$

So here m=2 and n=2

So number of positive divisors $=(2+1)\times (2+1)$ =9

So the number of positive divisors of $p^2q^2$ is 9
