Question

Find the value of x if​

Answer 1

Step-by-step explanation:

$\frac{125}{27} \times \frac{125}{27} ^{x} = \frac{5}{3} ^{18}$

$\frac{5}{8} ^{3} \times \frac{5}{8} ^{3x} = \frac{5}{8} ^{18}$

ᴄᴀɴᴄᴇʟ ᴛʜᴇ ʙᴀsᴇs sɪɴᴄᴇ, ᴛʜᴇʏ ᴀʀᴇ sᴀᴍᴇ.

$3 + 3x = 18$

$3x = 18 - 3$

$x = \frac{15}{3}$

$x = 5$
