Answer:
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

Answer:
45
Step-by-step explanation:
we know the number is two digits.
we know that the sum of the digits is 9
therefore, the only possible numebrs are:
18, 81
27, 72
36, 63
45, 54
we also know that the inverse of the digits is the original number plus nine
therefore, 18 and 81 are out
27 and 72 are out
36 and 63 are out
the only numbers left are 45 and 54.
since 45+9=54, the number is 45.
