Q. Fully simplify using only positive exponents.12x4y430x3y7Answer:
Simplify Coefficients: Simplify the coefficients (numerical parts) of the expression.Divide 30 by 12 to simplify the coefficient.30÷12=2.5 or 25
Simplify x Terms: Simplify the x terms using the laws of exponents.Subtract the exponent in the denominator from the exponent in the numerator for x.x(3−4)=x−1Since we want only positive exponents, we can write x−1 as x1.
Simplify y Terms: Simplify the y terms using the laws of exponents.Subtract the exponent in the denominator from the exponent in the numerator for y.y(7−4)=y3
Combine Coefficients and Variables: Combine the simplified coefficients and variables. (25)⋅(x1)⋅y3
Final Simplified Expression: Write the final simplified expression with only positive exponents. 2x5y3
