L'exo trop facile❤❤❤

Your thumbnail is wrong

7x7. 49

easy to guess 5 is a factor and then it becomes a quadratic

Anybody else triggered by the way this person writes "x"?

4^x+4^x=16 2(4^x)=16 4^x=8 (2^2)^x=2^3 2^2x=2^3 log2(2^2x)=log2(2^3) 2x=3 x=1.5

Lol what is this 7th grade?

4^x+4^x=16 2(4^x)=16 4^x=8 log_4(x)=log_4(8) x=log_4(8) log_4(4*2)=log_4(4)+log_4(2) log_4(4)=1 1+log_4(2) 1+log_2(2)/log_2(4) log_2(2)=1 log_2(4)=2 1+(1/2) 1.5

I calculated under 5 second so easy

Simpler way: 4^x+4^x=16 2*4^x=16 2*2^2x=16 Therefore 2^2x+1=2^4 Comparing exponents: 2x+1=4 x=3/2 This was wayyyy easy

😍😍😍

😮😮😮

Was it necessary to to multiply (2√3)^x on both sides? Can you explain that? I thought this was a standard exponential question.
