How do you evaluate #ab+abs(-40)# when a=0, b=3?

Answer 1

Gianna Caruso

The result is #40#.

Enter the values, multiply, and then determine the absolute value:

#color(white)=>ab+|-40|#

#=>(0)(3)+|-40|#

#=0+|-40|#

#=|-40|#

#=40#

To evaluate the expression ( ab + |ab| ) when ( a = 0 ) and ( b = 3 ), we substitute the values of ( a ) and ( b ) into the expression:

( ab + |ab| = (0)(3) + |(0)(3)| = 0 + |0| = 0 + 0 = 0 )

Therefore, the value of the expression is ( 0 ).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
