Simplify: 6 + (5 + 4) * 3

33

Step-by-step explanation:

Remember PEMDAS when using order of operations.

Parentheses Exponents Multiplication Division Addition Subtraction.

1. Solve what's in the parentheses first:

5+4 = 9

2. Multiply what's in the parentheses by 3.

9 x 3=27

3. Add 6

27+ 6 = 33

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
