can i do this question in the same way?For question 11 (a), use your calculator. If you are having a CASIO calculator of the fx brand use this method:
1. Use the In function
2. Enter the following into your calculator: In 0.125/In 2
For (b):
1. Change 512 to 2^9 so that all the numbers have the number 2 with a power.
2. Then do an equation:
4n+2n=9
3. Find the value of n
6n=9
n=9/6
n=1.5
Hope this was clear to you.
