Q. Write the expression as a fraction with a positive exponent. y31
Understand Problem: Understand the problem with negative exponents.To write the expression with a positive exponent, we need to recall the rule that a−n=an1 for any nonzero number a and positive integer n. This means that we can rewrite y−3 as a fraction with y in the denominator and a positive exponent.
Apply Rule: Apply the negative exponent rule.Using the rule from Step 1, we can rewrite y−3 as y31. This is because the negative exponent indicates that y should be in the denominator and the exponent should be positive.
