1. 2(2)(3) + 3(3)(1) + 5(2)(1) = 31
2. 2(2 + (3)(1)) + 4((2)(3) + (2)(1)) = 42
I assumed you meant "What is 300 <em>to </em>the power of two," or 300².
We can think of exponents as repeated multiplication in the same way as we think of multiplication as repeated addition: Just as 300 · 2 means 300 + 300, 300² means 300 · 300.
When we work this out, we find that 300² = 300 · 300 = 90,000
The main rule we use in this exercise is
and the more general case:
Using these rules, we make all the indices, or exponents, look like
, and compare them to each other.
