(a)
1. Let x = the repeating decimal. (a) x = 0.151 515 151 5…
2. Multiply
x by the power of 10 that
contains the same number of zeros as
there are digits in the repeating pattern.
The pattern contains 2 digits so
multiply by 100.
100
x = 15.151 515 15…
3. Subtract
x from the new value. 100x - x = 15.151 515 15 - 0.151 515 15

What is scientific notation used for?
It's a shorthand way to express large numbers or even very small numbers.Example:44800000000 = 4.48e+10
What is infinity to the infinity?
Presuming you are using limits, the exponentiation of two limits which diverge to infinity, also diverge to infinity. Or, using shorthand notation: ∞∞= ∞
How does scientific notation help scientists?
Scientific Notation helps scientists write big or small numbers in a shorthand way. For example, instead writing 5,230,000,000,000 it would just be easier to write 5.23 x 10 to the 14th power.
How much is 1.0e?
The notation "1.0e" is typically shorthand for scientific notation, where "e" stands for "exponent." However, it is incomplete without a number following the "e." For example, "1.0e2" would equal 100, while "1.0e-2" would equal 0.01. If you meant "1.0e0," it equals 1.0.
What number is this roman numeral Mcmlii?
In modern (shorthand) notation, M = 1000, CM = 900, L = 50, II = 2 the sum is 1952.In the ancient Roman (full) notation, M = 1000, C = 100, M = 1000, L = 50, II = 2 the sum is 2152.Remember as the Romans used Roman Numerals there in no place order, you just add the values of the letters. Monks in the Middle Ages created the modern (shorthand) notation with place order to save time and ink when making copies.

Exponents Example: 12x12x12=123
What is the shorthand notation for the electron configuration and germanium?
The shorthand notation for the electron configuration of germanium is [Ar]4s2 3d10 4p2. This notation indicates that germanium has the same electron configuration as argon (Ar) up to its 18 electrons, followed by the 4s and 3d electrons before the 4p electrons.
