e=3.
So this is how I approached this. Since 7 is being multiplied, I divided both sides by 7 so 105/7 = 15. Then it becomes simple as 5e=15. We divide both sides by 5 and get e=3. Tip: just try isolating the variable and then life is much easier.
The total numbers with 10 digits are 9*10*10*10*10*10*10*10*10*10 = 9*(10^9)
If you are restricted to use no 1s, the numbers are 8*(9^9)
Then, the probability is : numbers with no 1s / total numbers
= 8*(9^9) / [9*(10^9)]= 0.344
Answer:
2
Step-by-step explanation:
15 - 3 = 12 / 6 = 2
Is this the whole question?
Answer:
10
Step-by-step explanation:
Prime factorize 100 = 2 * 2 * 5 * 5
√100 = √2*2*5*5 = 2*5 = 10
