Question

(0) 3ab + 4bc - 5ca when a = 4, b = 5 and c = 2 ​

Answer 1

Answer:

We will get the value is 60.

Step-by-step explanation:

• We have to evaluate the above expression by using the given data.

       Given data:- $a=4,b=5,c=2.$

        To find:- Value of $3ab+4bc-5ca.$

       Solution:-

• To solve the above equation we will follow the BODMAS rule.

• BODMAS is an order of mathematic operations.

• BODMAS rule is to be followed while solving expressions in mathematics. It stands for,

           B= bracket

           O= order of power or rules

           D= division

           M= multiplication

           A= addition

           S= subtraction

      Now put the value a and b,c in the given equation we get,

            $3ab+4bc-5ca\\=>3(4)(5)+4(5)(2)-5(2)(4)\\=>60+40-40\\=>100-40\\=>60$

    Here the question will be to find the value of $3ab+4bc-5ca.$
