Equations involving Indices

[TomTom-ywpm]

Answer for (C) is 5∛5 in its simplest form.
5x=125x¯¹/²
x=25x¯¹/²
x ÷x¯¹/²=25
x¹+¹/²=25
x³/²=25; squaring both sides
x³=625 ; taking cubic root
x= (5*5*5*5)¹/³
x= 5∛5

Clear explanation may good lord may bless you

[jwbkliz]

Great work sir, help on this question.if A+B+ C=180°, show that, sin2A+sin2B+sin2C=2sin(A+B) cos(A-B)+2sinC cosC.

Hw did u even cross multiply those things

[Hotties]

Great maths work out but more detailed explanations required

[Emmanueloffor-zc]

Sorry please how is 2 raised to the power of 3 8 isn't it meant to be 2 raised to the power of 4

[rdjjbcw]

Thanks for helping me to solve my question sir

[richardkapalu]

Do clear calculations on question b when cross multiplying ❤ 3:11

[brandonfox]

For a), I took a more complicated approach that involved using logarithms and I also ended up getting x = 5/2 (or x = 2.5).

Thank you so much this video is very helpful

[ocosjtw]

But I think u made a mistake on part 2 sir while cross multiplying

[Tumusiime-mqnk]

Aaaaa how can you multiply 1/x^4=625 and just make inter changes

[AleshaSeverinus]

I don't understand letter b sir
I need help

[BrandiSecondarySchool]

How can I calculate this:
2 to the power of 5x - 1 = 1/8 to the power of x(x - 1)

[lqlyneg]

this mathematics is for engineering mathematics or what

[jxnjkjk]

When a question is giving maybe 5×+1=625, how will you solve it

[HumphreyMulenga-rbbd]

I want you to solve for me (1/3 )-1

[ananiasyohana]

Solve this 2 rest to power x minus y equal to 16

[Obenewaa]

Am I the only one who is confused here
