Q. Simplify the expression:\newline7z2+3z27z^2 + 3z^2 \newline ______
  1. Given expression: We are given the expression 7z2+3z27z^2 + 3z^2. To simplify this expression, we need to combine like terms. The like terms here are 7z27z^2 and 3z23z^2, which both have the variable zz raised to the power of 22.
  2. Combining like terms: To combine the like terms, we add the coefficients (the numbers in front of the variables) together. The coefficients are 77 and 33.\newline7z2+3z2=(7+3)z27z^2 + 3z^2 = (7 + 3)z^2
  3. Performing addition: Now we perform the addition of the coefficients. 7+37 + 3z^22 = 1010z^22
  4. Simplified expression: The expression is now simplified to 10z210z^2, which is the sum of the like terms.
