Question

If 2× 3= 812, 4 ×5=1620 then 6×7= ?

Answer 1

Answer:

$2428$

Step-by-step explanation:

Given that $2*3 = 812$ , $4*5=1620$

This is in the form of 400a + 4b

⇒$400(2)+ 4(3)=812$

⇒$400(4) + 4(5)=1620$

⇒$6*7= 400(6) + 4(7)$

⇒$2428$

Answer 2

The answer is 421.

The pattern that seems to be followed here is that the product of the two numbers is equal to the concatenation of the two numbers with an "1" in between them. Using this pattern, we can find the answer to 6×7 as follows:

2 × 3 = 6, so we can represent this as "23" with an "1" in between.

4 × 5 = 20, so we can represent this as "45" with an "1" in between.

Therefore, we can assume that 6 × 7 will be equal to "67" with an "1" in between. Combining "67" and "1" gives us the answer of 6 × 7 = 421.

Therefore, the answer is 421.
