Answer:
log₁.₅3 or 2.70951
Step-by-step explanation:
- 3^(2x) - 2^(x + 1) * 3^x - 3*2^(2x) = 0
- 3^(2x)- 2*2^x*3^x + 2^(2x)- 4*2^(2x)=0
- (3^x-2^x)^2 - (2*2^x)^2=0
- (3^x-2^x+2*2^x)(3^x - 2^x - 2*2^x)=0
- (3^x+2^x)(3^x- 3*2^x)=0
- 3^x+2^x>0 for any value of x
- 3^x- 3*2^x=0
- 3^x= 3*2^x
- 3^x/2^x=3
- 1.5^x=3
- x= log₁.₅ 3 = 2.70951
Answer:
826
Step-by-step explanation:
82.6 x 10 to the power of 2 :
8.26 * 10^2
8.26 * (10 * 10)
8.26 * (100)
= 826
