Answer:

Step-by-step explanation:
In the geometric series:

The nth term of the geometric sequence can be calculated using formula

In your case, n = 10, then

Remember property of exponents

add exponents of same base
ok so
50,000 is 5 times 10^4
so
50000 times 10^15=
5 times 10^4 times 10^15=
5 times

=
5 times 10^19
Answer:
P= 30 cm
Step-by-step explanation:
Formula for Rectangle Perimeter P=2(l+w)
P=2(10+5)
P=2(15)
P=30
.33 in its simplest form is 1/3 I think
