The potato tuber moth (Phthorimaea operculella) is a significant pest of potato tubers. It affects potatoes both in the field and during storage. The adult moths lay their eggs on the potato leaves, stems, and tubers.
If (x+1/x)2 = 3 Then the value of
x96 + x66 + x42 + x18 + x12 + 1 is
If x2 - 7x + 1 = 0, then determine the value of:
If (a + b) = 7 and ab = 9, then find the value of (a2 + b2).
If x – 1/x = 9, then x3 – 1/x3 is:
Find the value of ‘x’ in the given expression
(49/16)x × (64/343)x-1 = 4/7
If x = 15
find x 5 - 16 x 4 + 16 x 3 - 16 x 2 + 16 x - 16 = ?
Find the values of x and y if 0.1x + 0.05y = 20 and 0.3(x+2) +0.6y = 66.
If a – b – c = 0, then the value of (a2 + b2 + c2)/(b + ac) is:
(123×123×123 + 130×130×130)/(123×123 - 123×130 + 130×130) = ?
