Question

find the value of each of the following:
1.(7909 x 98)+(7909 x 2)
2.(43987 x 45) x (43987 x 55)

Answer 1

Direct answer

1.--->7,59,264

2.--

Answer 2

Answer:

1. We can use the distributive property of multiplication to simplify the expression:

(7909 x 98) + (7909 x 2) = 7909 x (98 + 2) = 7909 x 100

Using multiplication, we get:

7909 x 100 = 790900

Therefore, (7909 x 98) + (7909 x 2) = 790900.

2. We can use the distributive property of multiplication again to simplify the expression:

(43987 x 45) x (43987 x 55) = (43987 x 43987) x (45 x 55)

Using multiplication, we get:

(43987 x 43987) x (45 x 55) = 1936488369 x 2475

We can use long multiplication to calculate this product:

= 479046324378975

Therefore, (43987 x 45) x (43987 x 55) = 479046324378975.
