3! 3x2x1=6
Yes, the factorial (\(3!\)) must be calculated first.
In mathematics, a factorial (\(!\)) is a unary operation (a function applied to a single number). It has a higher precedence than standard binary operators like multiplication, division, addition, and subtraction.
-999
-999 by moving bottom left side pencil of 8 & move in front of 9 as a - making 8 a 9. Move bottom pencil of the 5 to top right side of 5 making a 9.

D 299 answer
Part 3:
3Factor out \(2^{99}\) (think of \(2^{99}\) as a single variable \(x\), so \(2x - 1x = 1x\)):
\(2^{99}\cdot (2-1)\)

\(2^{99}\cdot (2-1)\)
D 299 answer
Part 2:
1Rewrite \(2^{100}\) using exponent rules (\(a^{m+n} = a^m \cdot a^n\)):
\(2^{100}=2^{99+1}=2^{99}\cdot 2^{1}\)
2Substitute this back into the original expression:
\(2\cdot 2^{99}-2^{99}\)

The correct answer is D (\(2^{99}\)).
Step-by-Step Solution
To solve \(2^{100} - 2^{99}\), we can use the rules of exponents to factor out the common term:
