Question

solve the following using suitable properties102*[-45]​

Answer 1

Answer:

100*(-42)+2*(-42)=-4200+ (-84)=-4284

102=100+2

Answer 2

Step-by-step explanation:

Given :-

102×(-45)

To find :-

Solve 102×(-45) by using suitable Property?

Solution:-

Given that

102×(-45)

It can be written as

=> (100+2)×(-45)

We know that

Distributive Property :

If a and b and c are three integers then a×(b+c) = (a×b)+(a×c) is called distributive Property

=> (100×-45)+(2×-45)

=> (-4500)+(-90)

=> -4500-90

=> -4590

Answer:-

The value of 102×(-45) = -4590

Used formulae:-

DiDistributive Property :

If a and b and c are three integers then a×(b+c) = (a×b)+(a×c) is called distributive Property under multiplication over addition.

a×(b-c) = (a×b)-(a×c) is called distributive Property under multiplication over Subtraction.
