The number 223 in base 5 represents a value in the base-5 numeral system. To convert it to decimal (base 10), you calculate (2 \times 5^2 + 2 \times 5^1 + 3 \times 5^0), which equals (2 \times 25 + 2 \times 5 + 3 \times 1 = 50 + 10 + 3 = 63). Therefore, 223 in base 5 is equivalent to 63 in decimal.
To calculate (5^{8} - 2 \times 3), first find (5^{8} = 390625). Then, calculate (2 \times 3 = 6). Finally, subtract: (390625 - 6 = 390619). Thus, the value is (390619).
The value of (5C2) is calculated using the combination formula (nCr = \frac{n!}{r!(n-r)!}). Here, (n = 5) and (r = 2), so (5C2 = \frac{5!}{2!(5-2)!} = \frac{5!}{2! \cdot 3!} = \frac{5 \times 4}{2 \times 1} = 10). Thus, (5C2 = 10).
In 2573 it is worth 500 and in 6459 it is worth 50, so 500 is ten times 50.
The expression "5 r²" represents five times the square of a variable ( r ). It is an algebraic expression and does not have a specific numeric value unless ( r ) is defined. For example, if ( r = 2 ), then ( 5 r² = 5 \times (2^2) = 5 \times 4 = 20 ).
5a = a + a + a + a + a
2 * abs( 5 - 4 ) * abs ( 2 + 3 ) = 10 Absolute value is the distance of a number from zero. So, if the math inside the absolutes is negative, it will become positive. In this case, it's not negative. After we do 5 - 4 and 2 + 3 we get... 2 * 1 * 5 We can get rid of the 1 because it's the multiplicative identity and won't change our answer any. 2 * 5 = 10
y = 2x + 5 17 = 2x + 5 X = 6
If you mean: 2x+5+3x = 25 then the value of x works out as 4
