Question

Use the numbers listed at the top (1,4,9,16,25,36,49,64)

you could use as many as you want just make them equal these numbers


_____________________=81

________________=100

___________________=121

_____________________=144

___________________=169

Answer 1

Let us use the given numbers to fill the blanks

Multiplying 9 with 9

9 x 9 =81

Multiplying 25 with 4 we get 100

25 x 4=100

121 can be obtained by finding the product of 25 and 4. This gives 100 . now lets add 25 to it , we get 125. Now lets subtract 1 from 125.

This can be written as

(25 x 4) +25 - 4 = 121

Multiplying 16 and 9

(16 x 9)= 144

169 can be obtained by finding the product of 25 and 4. This gives 100 . now lets add 64 to it , we get 164. Now lets and 4 , we get 168. Finally lets add 1 to get 169. This can be written as

(25 x 4) + 64 +4+1 =169
