Find the Domain of the following exponential and logarithmic equations and solve them:

kakasveta [241]

The base of a logarithm should always be positive and can't be equal to 1, so the domain is 0 < x < 1 or x > 1.

$\log_{\frac1x}243=5$

Write both sides as powers of 1/x :

$\left(\dfrac1x\right)^{\log_{\frac1x}243}=\left(\dfrac1x\right)^5$

Recall that $a^{\log_ab}=b$ , so that

$243=\left(\dfrac1x\right)^5$

$243=\dfrac1{x^5}$

$x^5=\dfrac1{243}$

Take the 5th root of both sides, recalling that 3⁵ = 243, so

$x=\sqrt[5]{\dfrac1{243}}=\boxed{\dfrac13}$

I need help on this problem

chubhunter [2.5K]

The value of x
3x°+46°+(2x-1°)=180°(angle sum of △)
5x+45=180°
5x=180°-45
x=135÷5
x=27
x is 27

put x into angle B,we have
2(27)-1
=53

thus angleB is 53°

hope it helps c:

Answer:

x + 2(x + 1) = 8 --> x = 2

y = 2 + 1 = 3

3(9 + 2y) + 5y = 20 --> y = -7/11

x = 9 + 2(-7/11) = 85/11

3(-1 - 2y) + 5y = -1 --> y = -2

x = -1 - 2(-2) = 3
