Solve the equation x2 = 5.
x = 5
x = 25
x = 5–√
x = ±5–√

x = ±

Step-by-step explanation:

x²=5 -> x = ±

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

if you are looking for the unit rate then the answer would be 9 because unit rate is distance divided by time.
