Calculate the value of b if −52=b−12.
If f(x+1/x)=x²+1/x², then the value of f(3/2) is:
a) 5/4
b) 4/5
c) 1/4
d) -1/4
If a=√5+1√5−1and b=√5−1√5+1,the value of(a2+ab+b2a2−ab+b2)is :
Find the value of a and b if 1×5+2×52+3×53+.....x×5x=(4x−1)5a+1+b16
Simplify these expressions and find their values if x = 3, a = − 1, b = − 2.
(i) 3x − 5 − x + 9 (ii) 2 − 8x + 4x + 4
(iii) 3a + 5 − 8a + 1 (iv) 10 − 3b − 4 − 5b
(v) 2a − 2b − 4 − 5 + a
