If a = 3 and b = -1, find the value of the following expression.

The required answer is 54.

Step-by-step explanation:

Given that a = 3 and b = (-1) . And we have to find the value of 2a³ b⁴ .

In such kind of problems , just substitute the given values of a and b to get the required answer .

So here ,

= 2a³ b⁴.

= 2 × (3)³ × (-1)⁴.

= 2 × 27 × 1 .

= 54

54

Step-by-step explanation:

2(3)^3 x (-1)^4

2 x (3^3) x 1

2 x 27 x 1

54

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
