00:00Hi scholars, we are on to question 7. It says simplify and then you have three terms in indices.
00:09So usually for questions like this, it's either you get a value for n or you just get a number,
00:15you know, n cancels out and you get a number. So let's see the answer. So n cancels out,
00:244n minus 4n is 0, 3 raised to the power of 2, 9. Option B. Question 8, simple interest again,
00:35we've done such before. Question 9, yeah, all the options, all the answer options came in number
00:43lines. So first you solve the inequality and then you'll be able to get the correct number line.
00:51Yes, that's where we stop. You're welcome.
