Answer:
b
Step-by-step explanation:
I just know it's greater than 1
<span>Sqrt(5x) * Sqrt(x) + 3
= 5^(1/2) * x^(1/2) * x^(1/2) + 3
= 5^(1/2) *x +3
=5^(1/2)*x^(2/2) +3
=Sqrt(5*x^2) +2
So the answer is A </span>
How do you know if the equation for a problem is multiplication? Well, lets go and review: Multiplication is :<span>A </span>mathematical<span> operation performed on a pair of numbers in order to derive a third number called a product. For positive integers, </span>multiplication<span> consists of adding a number (the multiplicand) to itself a specified number of times. Thus </span>multiplying<span> 6. :)</span>
