Question

When a number is multiplied with 25 it gives 78125. Find the number and express it as a power of 5. What is the product if the number is multiplied by (-5) × (5)?​

Answer 1

25x= 78125

x= 78125/25=3125=5^5

3125×(-5)= -15625

3125×5=15625

3125×(-5)×5=-78125

Answer 2

Solution:-

Let the number be X.

Given that,

(X) × (25) = 78125

X= 3125

----> The required number is 3125.

Now,

3125= 5 × 5 × 5 × 5 × 5

= 3125= 5^5

Now, If the number was multiplied by (-5) × (5) then the product= (-5) × (5) × 3125

= -78125
