"5^2x+1 + 5^2x = 150"
First rewrite the "5^2x+1" as "5^2x • 5¹"
5^2x • 5¹ + 5^2x = 150
Second: Factor out the "5^2x"
5^2x(1•5+1) = 150
Third: Add the numbers inside the parenthesis then times it to "5^2x"
6(5^2x) = 150
Fourth: Divide both side by '6'
5^2x = 25
Five: Rewrite "25" as 5²
5^2x = 5²
Sixth: Solve for x
2x = 2 ~> x = 1
Therefore the value of "x" is 1.
Checking:
5^2(1)+1 + 5^2(1) = 150
5³+5² = 150
125+25 = 150
150 = 150
One of the best,we thank you sir ,god bless you
Thanks enough
Great lesson!
Thank you
The X of the last question is 37.25
Hello, can you please solve number e. Thank You.
Okay, I will post it today in the afternoon...
X = 1, i understood it when i realized, i need to split 150 by addition not multiplication 🤭@sirp-mathstutorial
Beautiful... I will still make a post on it today or tomorrow.
Please the 2. Eg 2 raised to the power x multiplied by 5 raised to the power x would give 10x squared not 10x but the first one is 10 x
I got an answer of x= 10 4 over 6
Indicial means the exponential.
Exactly... Indices or exponent or power.
2^x+1= 5 I got lost on this one since the the bases don't HV common base
Okay, I will make another video to explain it better, keep an eye on my channel.
@@Prosperousonlinemaths alright thank you
I see x as 1
Please sir I really need to see the answer I stocked on the road😢
