Solve the equation (3x2)(3x4)=36

kodGreya [7K]

Answer:

The solution to the equation will be:

$x=\sqrt[3]{2},\:x=-\sqrt[3]{2}$

$x = 1.26$ , $x = -1.26$

Step-by-step explanation:

Given the expression

$\left(3x^2\right)\left(3x^4\right)=36$

simplify

$9x^6=36$

Divide both sides by 9

$\frac{9x^6}{9}=\frac{36}{9}$

$x^6=4$

$\mathrm{For\:}x^n=f\left(a\right)\mathrm{,\:n\:is\:even,\:the\:solutions\:are\:}x=\sqrt[n]{f\left(a\right)},\:-\sqrt[n]{f\left(a\right)}$

$x=\sqrt[6]{4},\:x=-\sqrt[6]{4}$

solving

$x=\sqrt[6]{4}$

$=\sqrt[6]{2^2}$

Apply exponent rule: $\left(a^b\right)^c=a^{bc}$

$=\sqrt[6]{2^2}=2^{2\cdot \frac{1}{6}}$

$=\sqrt[3]{2}$

$= 1.26$

Thus,

$x=\sqrt[3]{2}$ (or $x = 1.26$ )

similarly solving

$x=-\sqrt[6]{4}$

$x=-\sqrt[3]{2}$ or ( $x = -1.26$ )

Therefore, the solution to the equation will be:

$x=\sqrt[3]{2},\:x=-\sqrt[3]{2}$

$x = 1.26$ , $x = -1.26$

2x2 + 6x + 1 = 0<br>pls solve this quadratic equation<br><br>

PolarNik [594]

Answer:

2x² + 6x + 1 = 0

Formula

$x=\frac{-b+/-\sqrt{b^{2}-4ac}}{2a}\\ \\$

a = 2

b = 6

c = 1

$x=\frac{-6+/-\sqrt{6^{2}-4*2*1}}{2*2}$

$x=\frac{-3+\sqrt{7}}{2}\\ \\x=\frac{-3-\sqrt{7}}{2}$
