Here is a way you can write an exponent on the phone (x^2) just so you don’t have to explain the 2 is an exponent
i am confused on where the exponent is supposed to be so could you please rewrite it and i will help you solve it!
Answer:
Option (2)
Step-by-step explanation:
Given equation is,
x⁴- 9x² + 8 = 0
Let x² = t
By substituting the value of x²= t in the equation,
t² - 9t + 8 = 0
t² - 8t - t + 8 = 0
t(t - 8) - 1(t - 8) = 0
(t - 1)(t - 8) = 0
(t - 1) = 0 ⇒ t = 1
(t - 8) = 0 ⇒ t = 8
Since, t = x²
x² = 1 ⇒ x = ±1
x² = 8 ⇒ x = ±2√2
Therefore, Option (2) will be the correct option.
Answer:
73.7
Step-by-step explanation:
14 +14 +23+22.7=73.7
To find out the answer, let's factor out -42 (as if it's a positive number).
42: 1 x 42, 2 x 21, 3 x 14, 6 x 7.
With these given factors and due to the product being negative, we will go on and off with them being negative to find which sum up to 11.
Let's try 1 and 42.
-1 + 42 = 41
-42 + 1 = -41.
1 x 41 is not our answer.
Let's try 2 and 21.
2 - 21 = -19
-2 + 21 = 19
2 x 21 is not our answer.
Let's try 3 and 14.
-3 + 14 = 11
3 - 14 = -11.
Your answer is:
-3 and 14 sum up to 11 and make a product of -42.
-3 and 14 are your numbers.
I hope this helps!
