If the number 1005x4 is completely divisible by 8, then the smallest integer in place of x will be:
Number = 1005x4 For the divisibility by 8, last 3 digit of a number is divide by 8 then number will be divisible by 8. So, last 3 digits = 5x4 For the smallest integer x should be 0 and 504 is divisible by 8. So, x = 0
If x = 107, then find the value of x(x2 - 12x + 48) ?
If x – 1/x = 9, then x3 – 1/x3 is:
If x = 15, find x5 - 16x4 + 16x3 - 16x2 + 16x - 16 = ?
if 3y-3/y=8 then find the value of y ² +1/y²
If 9x2 + 16y2 = 24xy, then find the ratio of ‘x’ and ‘y’, respectively.
If 0.125x3 +0.216y3 = 210 and 0.25x2 + 0.36y2 = 10.30 then find the value of 0.5x + 0.6y.
1/3 + 1/15 + 1/35 + 1/63 + 1/99 = ?
