Answer:

Explanation:

1. When multiplying, exponents must be added, not multiplied as shown in the problem.

Error:
3(-2)x^(2*4)

Correct:
3(-2)x^(2+4) = -6x^(6)

2. The coefficients have been added, not multiplied.

Error:
(4+3)a^(2+5)

Correct:
(4*3)a^(2+5) = 12a^(7)

3. The exponent was miscalculated.

Error:
x^(6+3)

Correct:
x^(6+3+1) = x^(10)

4. The exponent was miscalculated, the two values have different bases, so they cannot be calculated using that method.

Error:
6^(4+3)

Correct:
3^4*2^3 = (3*2)^3*3 = 3*6^3

Answer:

See below.

Explanation:

Question 1

Given:


\left(3x^2\right)\left(-2x^4\right)=3\left(-2\right)x^(2 \cdot 4)=-6x^8

Error:

The exponent product rule has been used incorrectly.

The exponents should be added not multiplied.

Correction:


\left(3x^2\right)\left(-2x^4\right)=3\left(-2\right)x^(2 +4)=-6x^6

Correct answer:


-6x^6

------------------------------------------------------------------------------------------

Question 2

Given:


4a^2 \cdot 3a^5=(4+3)a^(2+5)=7a^7

Error:

The numbers 4 and 3 have been added when they should have been multiplied.

Correction:


4a^2 \cdot 3a^5=(4 \cdot 3)a^(2+5)=12a^7

Correct answer:


12a^7

------------------------------------------------------------------------------------------

Question 3

Given:


x^6 \cdot x \cdot x^3=x^(6+3)=x^9

Error:

The exponent of the x-term has been ignored: x = x¹

Correction:


x^6 \cdot x \cdot x^3=x^(6+1+3)=x^(10)

Correct answer:


x^(10)

------------------------------------------------------------------------------------------

Question 4

Given:


3^4 \cdot 2^3=6^(4+3)

Error:

The exponent product rule is only applicable when the bases are the same: a⁴ · a³ = a⁴⁺³

Correction:


3^4 \cdot 2^3=81 \cdot 8=648

Correct answer:


648
