1) 6.6 * 3.3 = 21.78
2) (10^ - 2 )*(10^ - 4) = 10 ^ ( -2 - 4) = 10 ^ - 6
3) result: 21.78 * 10 ^ - 6
4) to convert to standard form run the period on space to the lef and multiply the ten base by 10 =>
2.178 * 10 ^ - 5
Answer: 2.178 * 10 ^ - 5
Answer:
x=4+√23 , 4-√23
Step-by-step explanation:
x^2-4x=4x+7
x^2-8x-7=0
now solving from quadratic equation
x=4+√23 , 4-√23
