What is the answer to this and why?
Anna007 [38]

Answer:

Step-by-step explanation

Evaluate the exponential expression: (2x)2nd power −3y2nd power =___, if x = 5 and y = 3.
damaskus [11]

ANSWER

A. 73

EXPLANATION

The given expression is

(2{x})^{2}  - 3{y}^{2}

We substitute x=5 and y=3 to obtain:

(2 \times 5)^{2}  - 3{(3)}^{2}  =  {10}^{2}  - 3 \times 9

This simplifies to,

= 100 - 27

= 73

The correct choice is A.
