16 lakh students in India use khan academy today. The number of users are expected to grow by 50% every year. How many students in India would be using Khan Academy two years from now ?

32,00,000

Step-by-step explanation:

We can use the formula

16,00,000 x 0.5 x 2 = 16,00,000

Total no. of students using Khan Academy after 2 years will be:

1600000 + 1600000 = 32,00,000

4.5

Step-by-step explanation:

First we can write 25 as 5^2 to make the bases the same.

So we get

5^2(2x-3)=(5)^2x+3

5^4x-6=5^2x+3

Since the bases are the same, we can set the exponents equal to each other and solve.

4x-6=2x+3

4x=2x+9

2x=9

x=4.5
