Answer:

Step-by-step explanation:

Find the number by which 4732 should be divided to get perfect square.

ElenaW [278]

Answer:

The required number is 7.

Dividing by this gives the perfect square 676.

Step-by-step explanation:

Finding the prime factors:

2) 4732

= 676 * 7

Now 676 is a perfect square so the answer is 7.

= 1283 * 4.

Aleksandr-060686 [28]

First you need to multiple minus in second bracket, also in other side you need to multiple - 3 in bracket

$7t - 2 + 3t - 1 = - 3 + 9t \\ \\ 10t - 3 = - 3 + 9t \\ 10t - 9t = - 3 + 3 \\ t = 0$
Final answer is 0
