I’ll tell you how to solve these so you can do it yourself easily. If you still don’t understand, tell me and I’ll help out more :)
The exponent—small number in the top corner of another number—means the number of times you multiply the number by itself.
Example:
3²
I have to multiply 3 by 3 twice, therefore I do 3x3 and get 9. 3² = 9!
The · is a multiplication sign and the parenthesis indicate you multiply as well.
I’ll do 4a for you:
I see the exponent is 2, so I have to write:
2/3 · 2/3
I solve that by multiplying the numerators (2x2) and the denominators (3x3).
2/3 · 2/3 = 4/9.
The answer is 4/9.
