53. Answer the following questions (hint: see your answers to the Bold questions.
You already have the answers to these questions, but it will be convenient if
you have them here in one place for reference.)
1,What is a general rule for simplifying expressions like xA xB? Explain where this rule
comes from
7 What is the general rule for simplifying expressions like
? Explain where this rule comes
from
2 What is another way or writing a negative exponent, as in the expression 2-3? Explain
where this rule comes from
4 What is the meaning of a zero exponent, as in 2°? Explain where this rule comes from
What is a general rule for simplifying expressions like (x4)" ? Explain where this rule
comes from
What is a general rule for "distributing" exponents in expressions like (xy)4? Explain
where this rule comes from
- Explain what x' means. Explain where this rule comes from
How you can decide whether to distribute exponents in these two expressions: (xy)4 and
(x + y)4?
9 What is the rule for determining how many solutions there might be to equations of the
form x" = B? Explain where this rule comes from.
What does a fraction exponent mean, and how is it useful for solving for x in equations like
10
xa = B ?
I hope you learned::
what exponential notation means, including negative exponents, fraction
exponents, and zero exponents
how to make sense of the rules of exponents, so that you don't have to
memorize them, but you can work them out on your own.
how the root symbol, v , is related to exponential notation
when you "plug in" a value for a variable, remember that if you are
plugging in a negative number, the negative number is INCLUDED in
what you are plugging in. So you would write in a parentheses around
the number so it's clear that the thing that is being raised to a power
includes the sign. To evaluate x when x = -2, you would NOT write
x = -23, you MUST write x = (-2)3
