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).
In 2573 it is worth 500 and in 6459 it is worth 50, so 500 is ten times 50.
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).
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
