Question

-1,6n^9a^2*(-1,1n^5a^4)

Answer 1

-1,6n^{9}*a^{2}*(-1,1n^{5}*a^{4}) = 1.76 * n^{14} * a^{6}

Answer 2

To simplify the expression, you can use the rules of exponents and multiplication:

First, multiply the numerical coefficients: -1 * -1.1 = 1.1

Next, apply the rule for multiplying variables with the same base (n and a) by adding their exponents:

n^9 * n^5 = n^(9+5) = n^14

a^2 * a^4 = a^(2+4) = a^6

Now put it all together:

1.1n^14a^6
