`2^b = 2`

State true or false : The value of ab is 8 when a = 3 and b = 2.

If the angles (2a-30^(@)) and (b+60^(@)) make a linear pair, find the values of a and b when a-b=30^(@)

Find the value of 2a^2+b^2+5 when a=2 and b=-1

Find the value of : a + 2b - 5c when a = 2, b = -3 and c = 1

Find the values of a\ a n d\ b if A=B , where A=[a+4 3b8-6] , B=[2a+2b^2+2 8b^2-56]

If |(a-b-c, 2a, 2a),(2b, b-a-c, 2b),(2c, 2c, c-a-b)|=(a+b+c)(x+a+b+c)^2 then the value of x is equal to (A) -2(a+b+c) (B) a+b+c (C) -(a+b+c) (D) 2(a+b+c)

If A= [[1,2],[3,4]] , adjA= [[4,a],[-3,b]] , then the values of a and b are: (a) a=-2, b=1 (b) a=2, b= 4 (c) a=2, b=-1 (d) a=1, b=-2

Find the values of a and b if A=B , where A=[[a+4,3b],[8,-6]],B=[[2a+2,b^2+2],[8,b^2-5b]]

The value of c for which the equation a x^2+2b x+c=0 has equal roots is (a) (b^2)/a (b) (b^2)/(4a) (c) (a^2)/b (d) (a^2)/(4b)
