The product of 2 and the second power of y in algebraic expression

1 answer:

8 0

Algebraic expression of product of 2 and the second power of y
=> Algebraic expression is a combination of integers (numbers), variables (a, b, c, x, y, ….), exponent (2 5 3 …) that is a rational number and algebraic operations like subtraction (-), addition (+), multiplication (x) and division (/).
=> Product – result of multiplication
=> second power of y = y2
=> 2 x y2

Thus, the algebraic expression of product of 2 and the second power of y is equals to 2 x y2

Answer:

D. 8/2 +(-10)² = 104

Step-by-step explanation:

To find which statements are true, evaluate the expression for the given variable values. You do this by putting the numbers in place of the respective variables, then doing the arithmetic.

The respective expression values are ...

A 83 ≠ 37 . . . . (4/2) +9² = 2 +81 = 83

B 31 ≠ 61

C 52 ≠ 61

D 104 =104 . . . . true statement
