Depends. It’s called an asterisk.
In math it’s used for multiplying.
So 5*5= 25
(2-5i)(3+i)
use foil method to expand it into standard form
6+2i-15i+5i^2
5i^2-13i+6
Number 12 what do you think we do first
Answer:
70, 140, 280, 350
Step-by-step explanation:
Obviously, it must have the factors 2, 5, 7 as a minimum, so the smallest value is 2×5×7 = 70.
Any of these primes can be added to the product. In increasing order, the smallest additional factors will be 2, 4, 5, 7, 8, 10, ...
So, the four smallest numbers with prime factors of 2, 5, and 7 are ...
70 = 2·5·7
140 = 2²·5·7
280 = 2³·5·7
350 = 2·5²·7
Answer:
The GCF for the variable part is ab².
GCF<em>Variable</em>=ab²
Multiply the GCF of the numerical part 5 and the GCF of the variable part ab².
5ab²
