Step-by-step explanation:

hope it's help you

• 3 cube root of 15625
• write last digit 5
• cube root means cancel last 3 digits
• remains 15 = 2^3 = 8 less than 15
• 25

Answer 2

Answer:

we will first seperate the no. in groups of 3 no. or less than it. We will also put a bar on every group like this-

__      ___

15       625,  now we will take the group 1st and check which no.s cube ends

                    with 5 (625) ans = 5

So the answer's 1st no. will be 5.

To find the second no. we will see the second group (15).

Now we will see in which cube roots does 15 fall

15 falls in 2 cube and 3 cube

In 2 and 3, 2 is the smallest, so our answer's 2nd number will be 2.

ANSWER = 25
