Solution
So,
If (3)a + b = 3 × 9 × 27 then (a + b)2 = ?
-
Solution
(3)a + b = (3)1 × (3)2 × (3)3
⇒ (3)a + b = (3)1 + 2 + 3 = (3)6
a + b = 6 ⇒ (a + b)2 = 36
If (3)x + 4 – (3)x + 2 = 8 than x = ?
-
Solution
(3)x + 4 – (3)x + 2 = (3)2 – (3)0
Comparing x + 4 = 2 ⇒ x = –2
x + 2 = 0 ⇒ x = –2
If then x = ?
-
Solution
=
So, x + 3 = –2x – 2
⇒ 3x = –5
-
Solution
{–(–3)2}–2 = ?
-
Solution
{–(–3)2}–2
⇒ {–9}–2 =
If = 2.24 then = ?

Solution
-
Solution
y2 = 5y
y = 5
-
Solution
(Let)
⇒ y2 = y + 1
⇒ y2 – y – 1 = 0
Clearly =
If then x = ?
-
Solution
⇒ 2x – 1 = – 3
2x = – 2
x = – 1
