What is q1?
Show answer
Simplify (3x2)3(3x^2)^3. [1 point]
What is q2?
Show answer
Write 0.000180.00018 in scientific notation. [1 point]
What is illegal scientific-notation coefficient?
Show answer
32×10432 \times 10^4 is not scientific notation. The coefficient must satisfy 1≤a<101 \le a < 10, so write 3.2×1053.2 \times 10^5.
What is wrong decimal direction?
Show answer
A negative exponent marks a small number, so 6×10−3=0.0066 \times 10^{-3} = 0.006, not 60006000.
