Sir next question answer is 3
27^x^1/x = 1/x^1/x
, 27=1/x^1^x
3^3=1/x^1/x
Therfore 1/x=3..


Thankyou

[trulysatyam]

27^x=1/x
3^3x=(1/x)^3x
x^3x 3^3x=1
(3x)^3x=1^1
On comparison, we get
3x=1
So, x=1/3☑️
Thankyou sir 🎉

In which class this series suitable for knowledge

[iampriyankar]

After 3:29
x^4=8
x^4=2^3
x=2^(3/4)
HW ans: x = 1/3 by hit and trial
btw: when will be your next session for class 11.

Sir I am studying at class nine I have done it without logarithm but the value of x is coming that 8 to the power 1/4

[sameergera]

by hit and trial its 1/3 but by taking ln both sides and making a graph the critical value is 1/e so it forms an intersecting graph

[PinakinSharma-gv]

For the video question we can simply write
x⁴=8
x=8¼

[boppanaharsha]

27^x=1/x
27=1/x^1/x
now, by applying logarithm on both sides
we get
3log3=1/xlog1/x
which makes 1/x=3
and hence giving the answer as x=1/3
