Pls help Describe how to find the product of the two terms 3x^2y^5 and 4x^3y^7
zvonat [6]

Answer:

12 x^5y^12

Step-by-step explanation:

3x^2y^5 * 4x^3y^7

Multiply the constants

3*4 = 12

Multiply the x terms

x^2 * x^3

We know a^b* a^c = a^(b+c)

x^(2+3) = x^5

Multiply the y terms

y^6 * y^7 = y&(5+7) = y^12

Put them back together

12 x^5y^12

Write a algebraic expression
iren [92.7K]

Answer:

1. a^{3}b^{4}.

2. 3Y^{2} - 6.

3. a + b + \frac{b}{a}.

4. 4(r + a) + 2(r - s).

5. 3(55 - w^{3}).

Step-by-step explanation:

1. The product of the third power of a and the fourth power of b = a^{3}b^{4}.

The 'third power of a' means 'a to the power 3' and 'fourth power of b' means 'b to the power 4'.

2. Six less than three times the square of Y means 3Y^{2} - 6.

Here, 'three times the square of Y' means 'product of 3 and Y to the power 2', and 'six less than' means 'subtract 6 from the expression'.

3. The sum of a and b increase by the quotient of b and a means a + b + \frac{b}{a}.

Here, 'quotient of b and a' means 'b divided by a'.

4. Four times the sum of r and a increased by twice the different r and s means 4(r + a) + 2(r - s).

Here, 'increased by' means 'addition' and 'different r and s' means 'r minus s'.

5. Triple the difference of 55 and cube of w means 3(55 - w^{3}).

Here, triple means 3 times. (Answer)
