p = 11 [4/5]

Step-by-step explanation:

 from the question

L = 2(1/2)  and  W = 3 (2/5)

we should solve  for p  when p =  2L + 2W

so from the expression

P = 2 ( 2 1/2) + 2 ( 3 2/5)

P = 2 ( 5/2) + 2 ( 17/5)

P = 5 + 34/5

Find the lowest common multiple (L.C.M.)

P = [25 + 34]/5

P = 59/5

P = 11 4/5

therefore the answer to the question p =  2L + 2W  is

P = 11 4/5 .

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870

step-by-step explanation:

given expression is .

now we need to simplify the given expression .

we know that square root is equivalent to the power 1/2. so that means we can take half of the exponents to get the square root of given expression.

expanding that will give a very very large number so let's keep answer in exponent form.
