Answer 2

Ответ:

Объяснение:

1)3,5*4^2-8^2=3,5*16-64=56-64=-8;

2) а)-6m^4n^2*5m^n^2*n^7=-30m^(4+3)*n^(2+7)=-30m^7*n^5

  b)(-6m^2n^5)^3=-216*m^6*n^15

Answer 3

1. To solve the expression 3.5 * 4^2 - 8^2, we follow the order of operations (also known as PEMDAS/BODMAS).

First, we evaluate the exponentiation: 4^2 equals 4 * 4, which is 16. Similarly, 8^2 equals 8 * 8, which is 64.

Next, we perform the multiplication: 3.5 * 16 equals 56.

Finally, we subtract: 56 - 64 equals -8.

Therefore, 3.5 * 4^2 - 8^2 equals -8.

2. Let's simplify the expressions:

a) To convert the expression into standard monomial form, we need to multiply the coefficients and combine the variables with the same base raised to different exponents.

Start with the coefficients: -6 * 5 equals -30.

For the variables, we multiply the bases (m and n) and add the exponents: m^(4 + 2) equals m^6. n^(2 + 7) equals n^9.

Putting it all together, the expression becomes -30m^6n^9.

b) To simplify the expression (-6m^2n^5)^3, we raise the entire expression inside the parentheses to the third power.

-6^3 equals -216.

For the variables, we multiply the exponents by 3: (m^2)^3 equals m^(2 * 3) equals m^6. (n^5)^3 equals n^(5 * 3) equals n^15.

Combining the coefficients and variables, the expression simplifies to -216m^6n^15.
