Q. Simplify the following expression to simplest form using only positive exponents.(64x−18y21)35Answer:
Apply Power Rule: Apply the power to each factor inside the parentheses.We have the expression (64x−18y21)35. According to the properties of exponents, when we have a power raised to another power, we multiply the exponents. We will apply this rule to each factor inside the parentheses separately.6435 * x−18∗35 * y21∗35
Calculate Exponent for x: Calculate the exponent for x. We need to multiply the exponent of x, which is −18, by 35. x(−18×35)=x−30
Calculate Exponent for y: Calculate the exponent for y.We need to multiply the exponent of y, which is 21, by 5/3.y(21×5/3)=y35
Simplify Exponent for 64: Simplify the exponent for 64.We need to calculate 64 raised to the power of 35. Since 64 is 43, we can rewrite this as (43)35.(43)35=43⋅35=45
Calculate 45: Calculate 4 raised to the power of 5. We need to calculate 45. 45=4×4×4×4×4=1024
Rewrite with Positive Exponents: Rewrite the expression with positive exponents.We have x−30, which has a negative exponent. To make the exponent positive, we take the reciprocal of the base and change the sign of the exponent.x−30=x301Now, we can rewrite the expression with only positive exponents:1024×(x301)×y35
Combine for Final Expression: Combine all the parts to write the final simplified expression.The final simplified expression is:1024⋅y35/x30
