Zorluk: KolayOperations with Variable Exponents

Connect each unsimplified exponential operation to its mathematically equivalent simplified form.

  • (3a2)(2a4)(3a^2)(2a^4)6a66a^6
  • 12a62a2\frac{12a^6}{2a^2}6a46a^4
  • (2a3)2(2a^3)^24a64a^6
  • 6a−26a^{-2}6a2\frac{6}{a^2}

Cevap

The correct pairings are: (3a^2)(2a^4) pairs with 6a^6, (12a^6)/(2a^2) pairs with 6a^4, (2a^3)^2 pairs with 4a^6, and 6a^-2 pairs with 6/a^2.
Each pair represents a fundamental rule of exponents applied to a one-step algebraic expression involving both coefficients and variables.

Adım Adım Çözüm

1
Evaluate the product (3a2)(2a4)(3a^2)(2a^4).
6a66a^6
By the product rule, multiply coefficients (3×2=63 \times 2 = 6) and add the exponents of the same base (2+4=62 + 4 = 6).
2
Evaluate the quotient 12a62a2\frac{12a^6}{2a^2}.
6a46a^4
By the quotient rule, divide coefficients (12÷2=612 \div 2 = 6) and subtract the bottom exponent from the top exponent (6−2=46 - 2 = 4).
3
Evaluate the power (2a3)2(2a^3)^2.
4a64a^6
By the power of a product rule, apply the exponent to both the coefficient (22=42^2 = 4) and the variable (3×2=63 \times 2 = 6).
4
Evaluate the negative exponent expression 6a−26a^{-2}.
6a2\frac{6}{a^2}
By the negative exponent rule, a−2a^{-2} becomes 1a2\frac{1}{a^2}. The coefficient 6 is not raised to the negative power, so it stays in the numerator.
