SUMMARY

The discussion focuses on solving mathematical equations, specifically (3 3/8) to the power of -1, and two additional equations involving variables X. The first equation can be simplified by converting the mixed number into an improper fraction and applying the property of negative exponents, which indicates that (a/b)-1 equals (b/a). The second equation requires clarification on its structure, as it may involve different interpretations based on the placement of parentheses. Clear definitions and proper notation are essential for accurate problem-solving.

PREREQUISITES
  • Understanding of negative exponents in algebra
  • Ability to convert mixed numbers to improper fractions
  • Familiarity with algebraic expressions and equations

How would I solve these equation:

(3 3/8) to the power of -1

3X / X-1 + 4 = X / X+1

5 / X+2 + X(X+3) / X (Square) - 4

I been really stuck on these.

Thanks

What have you tried to do? I notice that you haven't even told us what you are supposed to do! You say "How do I solve these equation?" but only one of them is an equation! I can make a few guesses.

Can you write [itex]3\frac{3}{8}[/itex] as a single, improper, fraction? Do you know what a -1 power does to a fraction? [itex](\frac{a}{b})^{-1}= ?[/itex]

Do you mean 3X/(X-1)+ 4= X/(X-1)? What happens when you multiply a fraction by its denominator?

5 /(X+2) + X(X+3) / X2 - 4 or 5/(X+2)+ X(X+3)/(X2-4)?
What were you told to do with this?
