If you look at all of the numbers upside down then you get the sequence 86 ?? 88 89 90 91 so the ?? Will be 87, and the closest to upside down 87 is 18
Answer:
5
Step-by-step explanation:
5*10^5=500000 and 1*10^5=100000
You do 6/4, so the answer should be: 1.5 hours!
Answer:
d, e
Step-by-step explanation:
The applicable rules of exponents are ...
(a^b)(a^c) = a^(b+c)
a^-b = 1/a^b
__
In this case, it means the product is ...
(6^1)(6^0)(6^-3) = 6^(1+0-3) = 6^-2 = 1/6^2 = 1/36
__
The 6 without an exponent is equivalent to 6^1, an exponent of 1.
The sum of the exponents is -2.
Add the exponents to simplify the expression.
The value of the expression is 1/36.
An equivalent is any expression that results in 6^-2. One such is (6^5)(6^-7).
__
Only the last two choices, d and e, apply.
