Answer:

Given expression
4(x-3)+5x^(\bf -2) for x=2 is


4(x-3)+5x^(\bf -2)=-(\bf 11)/(\bf 4)

Explanation:

Given expression is
4(x-3)+5x^(-2) for x=2

Let f(x) be the given expression


f(x)=4(x-3)+5x^(-2)

now to find f(x) for x=2

ie., put x=2 in f(x) we get


4(x-3)+5x^(-2)=4(2-3)+5(2)^(-2)


4(x-3)+5x^(-2)=4(-1)+5(2)^(-2)


4(x-3)+5x^(-2)=-4+5* (1)/(2)^}2}


4(x-3)+5x^(-2)=-4+5* (1)/(4)


4(x-3)+5x^(-2)=-4+ (5)/(4)


4(x-3)+5x^(-2)= (-16+5)/(4)


4(x-3)+5x^(-2)= (-11)/(4)


4(x-3)+5x^(-2)=-(11)/(4)

Therefore the given expression
4(x-3)+5x^(-2) for x=2 is


4(x-3)+5x^(-2)=-(11)/(4)
