Example Given Find a or b

a = 20. b = ? c = 25

Find b or a. c^2 - a^2 = b^2

25^2 - 20^2 = c^2

625 - 400 = 225

Square Root of 225 is 15

QUESTION

a = 3 b = 4 c = ?

the answer is 5

Step-by-step explanation:

u what ?

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
