Penn Foster Algebra?

I’ve done four of the Penn Foster algebra exams with my sister’s help, but I’m stuck on Exponents And Roots and Algebraic Fractions. My sister doesn’t understand it either, and I don’t have anyone else to help me with it.

If you’ve done these exams and could help somehow I’d really appreciate it. These are the last two exams before I graduate so I really need help finishing them.

ok I hope you know math syntax! an exponent is like a power. Its how many times your number is multiplied by itself. Meaning 2^4 or two to the fourth power = 2 x 2 x 2 x 2 =16.

2 x 2 = 4

4 x 2 = 8

8 x 2 = 16

theres 4 twos up there. 2 to the 4th

ok roots they arent that bad. I hate figuring the larger numbers without a calculator but they are easy really. If you have say the number 49…..what times itself equals 49? 7 x 7 = 49 your root is 7. The root of 16 is 4 because 4 times itself (4 x 4 = 16). Think of all the double number multiples when dealing with roots.

1 x 1 =1

2 x 2 =4

3 x 3 =9

4 x 4 =16

5 x 5 = 25

6 x 6 = 36

7 x 7 = 49 ………….see what i mean here?
