Evaluate the expression:

1/3 (4x3) + 2^3

12

Step-by-step explanation:

1/3 (12) +8

4+8= 12

12

Step-by-step explanation:

we can use PEMDAS to find the solution to the expression, PEMDAS stands for:

Parentheses

Exponents

Multiplication

Division

Addition

Subtraction

we look at the expression and we see parentheses, so we solve whats inside of the parentheses

(4 x 3) = 12

1/3 (12) + 2³

now, we solve for the exponents in the expression

2³ = 2 x 2 x 2 = 8

1/3 (12) + 8

now we multiply the terms in the expression that need to be multiplied.

1/3 x 12 = 4

4 + 8

we have no division in the expression, so we skip that step and move onto addition, which will be our last step as there is no subtraction in the expression either

4 + 8 = 12

our answer to the expression is 12

7. d. 64

8. i. 32

9. c. 125

10. j. none of the above

11. d. 81

12. i. 216

13. e. none of the above

14. g. 240

15. e. none of the above

16. g. 32

17.   e. none of the above

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
