Thanks! Corrected!

how close is this to the actual HOAE test

The PSB HOAE test has exponents as part of the math section – these are for skills practice only.

nevermind. I figured it out. 1/0.125 is 1000/125=8. Math is my nemesis.. uggh.

Hello, I am looking for a good math book that teaches all the basic fundamentals of math for an adult (myself). I dropped out of high school so I missed out on learning percentage, fractions, etc. I now find math to be very intimidating. I probably need to start from the beginning so everything makes sense as I progress.

If you can recommend a book that also has worksheets to practice that would be lovely.

Thanking you in advance,

Mrs. Edwards

The answer is correct

3. 100

^{2}x 100^{5}= 100^{y}y=When multiplying exponents of the same base, add them – y = 7
