Answer:
9 plus 11 plus 12 =
Step-by-step explanation:
x is 22
Answer:
11
Step-by-step explanation:
Step 1: Parenthesis
6² - 5²
Step 2: Exponents
36 - 25
Step 3: Subtract
11
The dot is multiplication.
The population increases by a factor 1.0167 every year so the require figure is:
103 * 1 . 0167^5 = 112 million
The problem is asking you to simplify the exponents. When you multiply two or more powers with the same base, the exponents can be added and subtracted. In this case, the base is 7.

7 can also be written as

.

The answer would be 7³ if you kept the exponent, or 343 if you simplified further.
