7^3+7^x ➡7^3+x
the expansion of 7^3 = 343 so 343•7^x is also equivalent to the given expression.

5 animals are going towards the river .
<u>Step-by-step explanation:</u>
Here we have , One rabbit saw six elephants while going to the river. Every elephant saw 2 monkeys going towards the river. Every monkey holds one parrot in their hand.We need to find How many animals are going towards the river . Let's find out:
- 1 rabbit saw 6 elephants while going to the river. i.e. rabbit is only going towards river !
- Every elephant saw 2 monkeys going towards the river. From the sentence , each of the 6 elephants saw 2 monkeys going towards the river, hence will be 6 x 2 = 12 monkeys going towards the river.
But, the statement does not explicitly say that “Every elephant saw 2 DIFFERENT monkeys…”, therefore implicit rules apply and infer that the 2 monkeys are the same. So , every elephant saw 2 monkeys!
- Now , every monkey holds 1 parrot in their hands. 2 parrots are going towards the river.
So , total number of animals is :
⇒
⇒
Therefore , 5 animals are going towards the river .
