Exponents review

Home work today is to finish the worksheet we started in class. Homework tomorrow will be posted on this website so be sure you come back tomorrow for that.

On the last section of problems on the worksheet, there are some tougher problems.

c. 2-2 x 2n = 8. The 8 must be rewritten as 23. the equation then becomes:
2-2 x 2n = 23
Now figure out what n is equal to.

Question d. is the same way
d.7n x 74 = 1/49. Rewrite 1/49 as 7-2.
The equation then becomes: 7n x 74 = 7-2

Hope this helps with others.
