Answer:
How did Mandarin become the official language? All of the official spoken languages were once dialects. Mandarin was one of the 10 major dialects in China and it officially became the national language for China in 1911 after Dr. Sun Yat Sen overthrew the Qing Dynasty.
If we know that 180-5=128 that means that that equation must be equal to 128.
(2^3x+1)=128
By putting 128 into exponential form with a base of 2 you get 2^7:
(2^3x+1)=2^7
Since these have the same bases we can set the exponents equal to 7. This will give us an exponent of 3x+1=7. By Subtracting across and dividing by 3 you get:
3x=6 to 3/3x = 6/2
This gives us a final answer of:
x=2
