What is the value of 4370 × 461 - 4370 × 361 ?

If a , b , and c are three whole numbers then, a × ( b - c ) = a b - a c . Using this property, we can write, ⇒ 4370 × 461 - 4370 × 361 = 4370 × 461 - 361 = 4370 × 100 = 437000 Hence, the value of 4370 × 461 - 4370 × 361 is 437000 .

What is the value of 270 × 3 + 270 × 7 ?

If a , b , and c are three whole numbers, then by distributive property of multiplication over addition, we get, a b + c = a b + a c Using the distributive property, we can write, 270 × 3 + 270 × 7 = 270 × 3 + 7 = 270 × 10 = 2700 Hence, the value of 270 × 3 + 270 × 7 is 2700 .

What is the value of x ? 98 × 65 = x × ( 100 - 2 )

We need to find the value of x in 98 × 65 = x × 100 - 2 . Simplifying the operation inside the brackets, 98 × 65 = x × 98 Observe that in the right-hand side of the above equation, the order of the product has been changed. Using the commutative law, that is a × b = b × a , we can write, 98 × 65 = 98 × x As both sides of the equations should have the same value, we get the value of x as 65 .
