Step-by-step explanation:
The product is carbon dioxide and water
Ur output value is f(x).....so to do this problem u need to sub in 2/3 for f(x) and solve for the input value which is x
f(x) = -1/3x + 7
2/3 = -1/3x + 7 ...multiply everything by 3
2 = -x + 21
2 - 21 = - x
- 19 = -x
19 = x <== ur output
192 = 2 * 2 * 2 * 2 * 2 * 2 * 3 =
= 2^(6) * 3
√ 192 = √( 2^(6) * 3 =
= 2^(3) √ 3 = 8 √ 3 - in simple radical form.
( 8√3 ) ² = 64 * 3 = 192
Answer:
√ 192 = 8 √ 3
