I need help with this question:
2^4 + 2^4 + 3^5 +3^5 + 3^5
They somehow simplified it to tthis answer of 2^6 + 3^6
Also another similar question that I was having trouble with was:
2^(x) - 2^(x-2) = 3(2^13) what is the value of x
They got the answer of: 15`
need help with2^4 + 2^4 + 3^5 ...... Simplify

x-2=13
x=15

I understand how you did the first problem but I really don't follow what you are doing with the second solution can you please clarify....I am Stumped! thanks...and what do you think...would these questions be easy medium or hard?

what I was trying to do was to have an equation as below:nbpatel wrote:I understand how you did the first problem but I really don't follow what you are doing with the second solution can you please clarify....I am Stumped! thanks...and what do you think...would these questions be easy medium or hard?
A^X B^Y = A^Z B^W
So;
When the base numbers are the same, the power needs to be the same:
X=Z
Y=W

Can someone further explain how you simplify:nbpatel wrote:I need help with this question:

2^4 + 2^4 + 3^5 +3^5 + 3^5 ?

2^4 + 2^4 + 3^5 +3^5 + 3^5 ?
3^5 +3^5 + 3^5 = 3*(3^5)
since 2*2^4 = 2^5 and 3*3^5 = 3^6
so it is 2^5 + 3^6
edited: its like saying X+X = 2X and Y+Y+Y = 3Y

Perfect! Thank you so much
