Which expression and value represents 100 less than 3 times the sum of 18 and 2?
3 × (18 + 2) – 100; –44
3 × (18 + 2) – 100; –40
100 – 3 × (18 + 2); 40
100 – 3 × (18 + 2); 48

The point of an exponent is to show how many times something is multiplied together.  Since it is multiplied twice, the answer is 100^{2}

i have no clue at all sorry

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
