Answer:
10^2
Step-by-step explanation:
10^9/10^7 is the same as 10^9*10^-7 if you multiply two same bases you can add there exponents. So, 9+(-7)=2. So, it’s 10^2

Answer:
The denominator is all real numbers except 0.
Step-by-step explanation:
In the function f(x) = 1/x, x appears in the denominator. A denominator cannot be zero since division by zero is undefined.
To find what values of x must be excluded from the domain, set the denominator equal to zero, and solve for x.
x = 0
The denominator is all real numbers except 0.
16- let x represent the number:
x+ (x+1)+(x+2)=100
collect like terms
3x+3=100
3x=97
x=~32 but we need an odd number so round to 31, since 33 would be too great
31+33+35=99
therefore, the three numbers are 31, 33, 35
