উত্তরের বিবরণ
প্রশ্ন: log3√254√2 + log2√264 = ?
সমাধান:
log3√254√2 + log2√264
= log3√2(3√2)3 + log2√2(2√2)4
= 3 + 4
= 7
এখানে
54√2 = 27 × 2√2
= 33 ×(√2)3
= (3√2)3
64 = 26
= 24 × {(√2)2}2
= 24 × (√2)4
= (2√2)4

and xy = 45, find the value of x2 + y2 = ?
Solution:
Given that,
and xy = 45
We know,
x2 + y2 = (x - y)2 + 2xy
= 42 + 2 × 45
= 16 + 90
= 106

D
1
সমাধান:
{(x2y-1)/(x-2y)}2
= {(x2/y)/(y/x2)}2
= {(x2/y) × (x2/y)}2
= (x4/y2)2
= x8/y4
