A radical (square root of a number) is said to be in "simplest form" when all perfect squares have been

factored out and simplified: 32 can be factored as

✓16 - 2 which we can simplify to 16 72 which

we can simplify again to 4:72. Thereby, making the

number in the root the smallest number possible.

Always try to find the largest perfect square factor of the

radicand and write it as the first factor.

What are the first 20 perfect squares? Type them below.

the last choice

step-by-step explanation:

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b

time is equal to distance over rate so

t = d/r

need a little bit more information for the second question.
