What does this worksheet teach?
⌄
Name the base and exponent in powers with tricky signs, then write the expanded form, sign and value. The base is the number used as a repeated factor, and the exponent tells how many times it is used. A negative sign belongs to the base only inside parentheses. The directions on the page read: Fill in every column. Under Sign, write + or − to show the sign of the value. Write fractions in simplest form. An answer key is included.
Can I use this powers with negative and rational bases worksheet for homeschool or classroom?
⌄
Yes, both. We made it for 7th grade exponents, and it works the same at home or at school. At home, a student can work through it alone and then go over it with you, which shows quickly what is solid and what needs another look. In class it works as independent practice, homework or a warm-up, and you can print one copy or a full set.
Where does the negative sign go in a power?
⌄
Inside parentheses, it belongs to the base. Outside them, it applies after the power is found.
How do you simplify a power of a fraction?
⌄
Raise the numerator and the denominator to the exponent, then write the fraction in simplest form.
Do these worksheets include answer keys?
⌄
Yes, all 13 have an answer key.
