Answer:
1) C
2) A
3) D
Step-by-step explanation:
A) We substitute the values for a ,b , c and d in the given equation.[tex]\frac{6}{3} +4^2 (5) \\= 2+80\\=82[/tex]
Hence option c. 82 is the answer.
2) The product 6(-3)
Since positive x negative gives negative
we get -(6x3) = -18
Option A is the answer.
3) For this we have to find cube of a fraction with numerator 4 and denominator 7
We find cube of numerator first = 4x4x4 =64
Cube of denominator = 7x7x7 = 343
Hence cube of fraction = 64/343
Option D
