Step-by-step explanation:
![a^{-n}=\dfrac{1}{a^n}\\\\\text{therefore}\ 10^{-5}=\dfrac{1}{10^5}=\dfrac{1}{100000}=0.00001\\\\1.23\cdot10^{-5}=1.23\cdot0.00001=0.0000123](https://tex.z-dn.net/?f=a%5E%7B-n%7D%3D%5Cdfrac%7B1%7D%7Ba%5En%7D%5C%5C%5C%5C%5Ctext%7Btherefore%7D%5C%2010%5E%7B-5%7D%3D%5Cdfrac%7B1%7D%7B10%5E5%7D%3D%5Cdfrac%7B1%7D%7B100000%7D%3D0.00001%5C%5C%5C%5C1.23%5Ccdot10%5E%7B-5%7D%3D1.23%5Ccdot0.00001%3D0.0000123)
- move the decimal point <em>n</em> place to the left
- move the decimal point <em>n</em> place to the right
Examples:
![1.2\cdot10^5=1\underbrace{20000}_{5\to}=120,000\\\\1.2\cdot10^{-5}=0\underbrace{.00001}_{\leftarrow5}2=0.000012](https://tex.z-dn.net/?f=1.2%5Ccdot10%5E5%3D1%5Cunderbrace%7B20000%7D_%7B5%5Cto%7D%3D120%2C000%5C%5C%5C%5C1.2%5Ccdot10%5E%7B-5%7D%3D0%5Cunderbrace%7B.00001%7D_%7B%5Cleftarrow5%7D2%3D0.000012)
Slope = -5/4
y intercept = 1
The slope is always attached to x. The intercept is the number attached on the end.
Answer:
Step-by-step explanation:
b = 20 °
c = 160° ( b/c 180-20 = 160 ) :)
Answer:
LCM is the least common factor the number common in both and left numbers, Therefore, HCF and LCM of numbers 24 and 36 are 12 and 72 respectively.
Step-by-Step Explanation:
Find the prime factorization of 24
24 = 2 × 2 × 2 × 3
Find the prime factorization of 36
36 = 2 × 2 × 3 × 3
Multiply each factor the greater number of times it occurs in steps i) or ii) above to find the LCM:
LCM = 2 × 2 × 2 × 3 × 3
LCM = 72
No this number is not written in scientific notation
In scientific notation, it'll look like
4.8 * 10 ^14
In scientific notation it's 10 ^ n
NOT 100^n
