Pre Algebra With Pizzazz Answers
Exponents help please?
*I DON’T NEED YOU TO GIVE ME STRAIGHT ANSWERS*
I*’m doing a homework page (pre-algebra with pizzazz) and one of the questions is 10^-14 * 10^-2
What do you do when you multiply negative exponents?
Do you just add them if the base is the same or what?
Do you do the same if the base is the same and one exponent is negative and one is positive?
Thanks to anybody who answers this.
when you multiply exponents with the same base, you add exponents :
a^k*a^n=a^(k+n)
k and n are any number (negative or positive)
in your case:
10^(-14)*10^(-2)=10^(-14+(-2))=
10^(-14-2)=10^(-16)
