Q. Simplify the following expression to simplest form using only positive exponents.(36x−6y2)−25Answer:
Apply Negative Exponent Rule: Apply the negative exponent rule to the entire expression.The negative exponent rule states that a−n=an1. We will apply this rule to the entire expression (36x−6y2)−25.(36x−6y2)−25=((36x−6y2)25)1
Apply Power of Power Rule: Apply the power of a power rule.The power of a power rule states that (am)n=am∗n. We will apply this rule to each part of the expression inside the parentheses.(3625)(x−6∗25)(y2∗25)1
Simplify Exponents: Simplify the exponents.Now we will simplify the exponents by multiplying them.(3625)(x−15)(y5)1
Simplify Numerical Part: Simplify the numerical part of the expression. 36 is a perfect square, so we can simplify 3625 by taking the square root of 36, which is 6, and then raising it to the power of 5. (65)(x−15)(y5)1
Apply Negative Exponent Rule to x−15: Apply the negative exponent rule to x−15. The negative exponent rule states that a−n=an1. We will apply this rule to x−15. (7776)(x151)(y5)1
Combine Terms: Simplify the expression by combining the terms.Now we combine the terms under the single denominator.(x15y57776)1
Rewrite with Positive Exponents: Rewrite the expression with positive exponents only.Since we want only positive exponents, we will move x15 to the denominator.(7776)(y5)(x15)1
Check for Further Simplifications: Check for any further simplifications.There are no further simplifications possible, as 7776 is already in its simplest form, and there are no like terms to combine with x15 and y5.
