Answer:
The positive zero is 11
Step-by-step explanation:
Given in the question an equation,
f(x) =x² - 121
We are asked to find the positive zero of f(x)
means x > 0 for which f(x) = 0
so,
<h3> x² - 121 = 0</h3>
x² = 121
Take square root on both sides of the equation
√x² = √121
x = ±11
which means that x = 11 and x = -11
Since x > 0 so we will reject x =-11 and we will accept x = 11
4/7 = 12/21
12/21 = x + 3/21
9/21 = x

Hello,
2.0 x 10^-4 * 3.1 x 10^-20
Apply exponent rule:
a^b*a^c=a^b+c
= 10^-24
=2*10^-24 * 3.1
Apply exponent rule: a^-b=1/a^b
:10^-24=1/10^24
=2*3.1*1/10^24
Multiply fractions:
a * b/c = a*b/c
=3.1*1*2/10^24
Apply rule 1* a = a
=3.1 * 2/10^24
2/10^24=1/5^24* 8388608
Multiply fractions:
= 1 x 3.1/5^24 x 8388608
Apply rule 1* a = a
= 3.1/5^24 x 8388608
Covert elements to decimal form:
5^24= 5.96046...E16
Multiply: 5.96046...E16 * 8388608
= 5.0E23
= 3.1/5.0E23
Divide:
3.1/5.0E23=6.2E-24
Simply:
6.2 x 10^-24
