Answer 3

Solving the equation 2.25x6 - 3.13x6 + 0.89x6 = 0.01

To solve the equation 2.25x^6 - 3.13x^6 + 0.89x^6 = 0.01, we can combine like terms on the left side of the equation:

(2.25 - 3.13 + 0.89)x^6 = 0.01

Simplifying further:

(0.01)x^6 = 0.01

Now, we can solve for x by dividing both sides of the equation by 0.01:

x^6 = 0.01 / 0.01

x^6 = 1

To find the value of x, we need to take the sixth root of both sides of the equation:

x = ∛1

Therefore, the solution to the equation 2.25x^6 - 3.13x^6 + 0.89x^6 = 0.01 is x = 1.

Value of the expression 0.3bc^3 + 2bc^3 + cbc^2

To find the value of the expression 0.3bc^3 + 2bc^3 + cbc^2, we can combine like terms:

0.3bc^3 + 2bc^3 + cbc^2 = (0.3 + 2 + 1)bc^3 + cbc^2

Simplifying further:

(3.3)bc^3 + cbc^2 = 3.3bc^3 + cbc^2

Therefore, the value of the expression 0.3bc^3 + 2bc^3 + cbc^2 is 3.3bc^3 + cbc^2.

Writing the given monomial 0.064c^6 as the cube of another monomial

To write the given monomial 0.064c^6 as the cube of another monomial, we need to find a monomial whose cube is equal to 0.064c^6.

Taking the cube root of 0.064c^6, we get:

∛(0.064c^6) = 0.4c^2

Therefore, the given monomial 0.064c^6 can be written as the cube of the monomial 0.4c^2.

Can the monomial A be represented as the square of another monomial B if A = 8c^8? If yes, how?

To determine if the monomial A can be represented as the square of another monomial B, we need to check if the exponent of each variable in A is even.

Given A = 8c^8, the exponent of c is 8, which is even. Therefore, A can be represented as the square of another monomial B.

To find B, we take the square root of A:

√(8c^8) = 2c^4

Therefore, if A = 8c^8, it can be represented as the square of the monomial 2c^4.

Finding the product of the monomials (-4.2a^4b^3c)^2 * (-5abc)

To find the product of the monomials (-4.2a^4b^3c)^2 * (-5abc), we can multiply the coefficients and combine the variables:

(-4.2a^4b^3c)^2 * (-5abc) = (-4.2)^2 * (a^4)^2 * (b^3)^2 * c^2 * (-5) * a * b * c

Simplifying further:

(17.64) * (a^8) * (b^6) * c^2 * (-5) * a * b * c = -88.2a^9b^7c^3

Therefore, the product of the monomials (-4.2a^4b^3c)^2 * (-5abc) is -88.2a^9b^7c^3.
