Question

when a = 4 and b = -3 , find the value of 16 - a²​

Answer 1

16-a^2 ====16-16===0 the answer will zero

Answer 2

• As per the data given in the question, we have to find the value of the expression.

       Given data:- $a=4,b=-3.$

       To find:- Value of given expression $16-a^{2} .$

       Solution:-

• We know that Subtraction means taking away some value from another value.

• Subtraction is denoted by (-).

• Properties of subtraction are as follows:-

1. Subtracting a number from itself.
2. Subtracting 0 from a number.
3. Order property.
4. Subtraction of 1.

    Now put the value $a=4$ in the above equation.

       $16-4^{2} \\\Rightarrow 16-16\\\Rightarrow 0.$

    Hence we will get the value $0.$
