Answer:
Keep the base the same and then subtract the exponents.
Step-by-step explanation:
According to one of the law of indices, for given values a, m and n;
a^m/a^n = a^(m-n)
The base value which is a is maintained and the difference of exponents are taken. In indices division becomes subtraction.
Now given the expression
3^-6/3^-4
As we can see, both the numerator and denominator has the same base which is 3, therefore we will keep the base and take the difference of its exponents according to the law above:
3^-6/3^-4 = 3^(-6-(-4))
= 3^(-6+4)
= 3^-2
= 1/3^2
= 1/9
Y+9x-2=8
That's the answer because y=-5 as yku said so to make an equation yiu could use that and you already solved it so it's Y plus 9 multiplied by -2 is equal to 8 :)
6:5 it's basically just like a fraction that you're reducing.
