Answer 1

Answer:

(3×5+3×5)+(5×3-2×3)+5×2=30+9+10=49

Answer 2

Answer:  $\left(\left(1+3\right)\times5+2\right)\times2+5$

Step-by-step explanation:

To make 49 by using digits 2, 3 , 5 and 1.

We first add 1 and 3 , we get 4

1+3=4

Then , multiply 5 to this sum , we get 20

i.e. (1+3) x 5= 4 x 5=20

Then add 2 to the above expression , we get 22

i.e. (1+3) x 5+2=20+2=22

Then, multiply 2 to the above expression , we get 44

i.e. ((1+3) x 5+2) x 2=22 x2=44

Now, add 5 in the above expression , we get 49 as the required answer.

i.e. ((1+3) x 5+2) x 2+5=44+5=49

Required expression : ((1+3) x 5+2) x 2+5=44+5=49
