Answer:
I think the answer is 60 or 70 or 65
A number that can add up to 10 and multiplies to 11 is 1 since 11 is a prime number
The base is the number that the exponent is attached to. So ten squared, the base is ten.
25/80 + 24/80 = 49/80. 16 and 20 both go into 80. !6 goes in 5 times so you multiply 5 by 5. 20 goes into 80 4 times so you multiply 4 by 4. 24/80 + 25/80 = 49/80.
