The sum of the coefficients in the expansion of $(1 + x - 3x^2)^{3148}$ is

$x^5 + 10x^4a + 40x^3a^2 + 80x^2a^3 + 80xa^4 + 32a^5 = $

Which is larger: $(1.01)^{1000000}$ or $10,000$?

The sum of coefficients in $(1 + x - 3x^2)^{2134}$ is

If the coefficients of $x^2$ and $x^3$ are both zero in the expansion of the expression $(1 + ax + bx^2)(1 - 3x)^{15}$ in powers of $x$,then the ordered pair $(a, b)$ is equal to

By neglecting $x^4$ and higher powers of $x$, find the approximate value of $\sqrt[3]{x^2+64}-\sqrt[3]{x^2+27}$.
