Answer 1

Answer:

$6 \times \\ | > < = 43525759 - + 642 \times 656 \times - 6 - + - 9 {2134 {65}^{?} }^{2} | 35.2 \sqrt{52158} \times \frac{?}{?} \times \frac{?}{?} \times \frac{?}{?} \times \frac{?}{?} 656 \frac{ { {?}^{2} }^{2} }{?}$

Answer 2

Answer:

So the required answer is

$140 = {2}^{2} \times 5 \times 7$

$156 = {2}^{2} \times 3 \times 13$

$3825 = {3}^{2} \times {5}^{2} \times 17$

5005=5×7×11×13

7429=17×19×23

Step-by-step explanation:

(1)

Let’s take 140,

Now 140 can be expressed as 2×2×5×7.

So, 140=22×5×7

(2)

Let’s take 156,

Now 156 can be expressed as 2×2×3×13.

So, 156=22×3×13.

(3)

Let’s take 3825.

Now 3825 can be expressed as 3×3×5×5×17.

So, 3825=32×52×17.

(4)

Let’s take 5005,

Now 5005 can be expressed as 5×7×11×13.

So, 5005=5×7×11×13.

(5)

Let’s take 7429,

Now 7429 can be expressed as 17×19×23.

So, 7429=17×19×23
