What is the inverse of f(x)=2^x

GuDViN [60]

Answer:

Step-by-step explanation:

$f(x)=2^x$

$y = {2}^{x}$

$x = {2}^{y}$

${2}^{y} = x$

$ln( {2}^{y} )=ln(x)$

$yln(2)=ln(x)$

<h3> $\frac{yln(2)}{ln(2)} = \frac{ln(x)}{ln(2)}$ </h3><h3> $y = \frac{ln(x)}{ln(2)}$ </h3><h3> ${f}^{ - 1} (x) = \frac{ln(x)}{ln(2)}$ </h3><h3>Hope it is helpful...</h3>

Complete the following exercises by applying polynomial identities to complex numbers. Factor x2 + 64. Check your work. Factor 1

Mumz [18]

$x^2+64=x^2-(8i)^2=(x-8i)(x+8i)$

$16x^2+49=(4x)^2-(7i)^2=(4x-7i)(4x+7i)$

$(x+9i)^2=x^2+2x\cdot9i+(9i)^2=x^2+18xi+81i^2=x^2+18xi-81=x^2-81+18xi$

$(x-2i)^2=x^2-2x\cdot2i+(2i)^2=x^2-4xi+4i^2=x^2-4xi-4=x^2-4-4xi$

$(x+(3+5i))^2=x^2+2x(3+5i)+(3+5i)^2\\\\=x^2+6x+10xi+3^2+2\cdot3\cdot5i+(5i)^2\\\\=x^2+6x+10xi+9+30i+25i^2=x^2+6x+10xi+9+30i-25\\\\=x^2+6x+10xi+30i-16=x^2+6x-16+(10x+30)i$

$Used:\\i^2=-1\\\\a^2-b^2=(a-b)(a+b)\\\\(a+b)^2=a^2+2ab+b^2$

ANYONE KNOW THIS PLS HELP

Alona [7]

In left one)
the 3 angles are equal so the sides are equal then we can say
$(3 \div 2) \times x + 6 = (2 \div 5)x + 9$
then x is 30÷11

the right one) is exactly similar
